Ok, I'll bite. A lot of the stuff you've brought up is true, but some of it probably needs to be responded to. I understand the mindset of waiting because nothing is going to change, especially since we're not going to finish a suspect either way until the majority of LTPL is over, but while we're waiting to get rid of quagsire (or keep it (puke)) I don't agree with some of the arguments
I think the response to how good stall is (it's matchup based+ppl arent preparing+ppl use the same 6-7 mons that happen to lose to quagsire) is wholly inadequate. Sure, I absolutely don't deny stall is very powerful in matchup and it looks a lot worse to see the50mph have zero chance before the game's started than it might actually be if you dont think about how he didn't prep or whatever. But the idea that nobody is prepping and this is unfair to stall isn't one that I understand. Stall is still a pretty unhealthy matchup to have to deal with even if you do have the foresight to actually prepare a team that doesn't get boned by it. It's not really as simple as prep slightly for stall and it's not a huge threat, that used to be how it worked but no longer. When you say quagsire beats that one basket of mons that everyone uses, I see that as it beats a large percentage of the best stuff in the tier which severely limits your options on how to handle it. You've brought up rose spikes as an example of how to prep better for quag stall many times. I had tried making rose spikes earlier for just that reason, and I found out 2 things. First off it's pretty good vs quag stall. Second off roselia just really kinda sucks right now and leaves you a lot worse off versus offense.
There's lots of other mons that can break through quagsire for sure, that was just one example, and some of the mons actually do perform very well vs stall despite the fact that quag has 5 teammates to beat whatever random mon you gave grass coverage to. I'm sure people could adapt better to quag stall, but is this something you want to force the tier through? Because from what I've been seeing/testing with, it's not a good meta shift that makes the tier more open. It's a bad one that heavily restricts you and makes matchup a lot more crucial. That's not something very easy to demonstrate, but I think you described one of the best ways to get around at it. Most of the good shit in the tier absolutely hates quag, so you have a metagame where you're pulling up all this mediocre to bad stuff to handle it which doesn't help all that much versus a good team without quag. Not in every case for sure, but the amount of things that are consistently good vs quag stall and good as a whole are limited and these limits on building in a meta already saturated with threats is a significant strain. You need to have 3 mons on your team capable of hitting quag and 2 of those have to be safe switchins, ideally to scald, to not run into problems with team support. When you consider how many top things absolutely hate quag or hate the changes to their moveset this forces on them, that has become annoying for the meta to deal with so far. Not to mention, we're just talking about killing quag. Not the other 5 things on stall. All of which want to come in to wall ur HP grass mon of choice, and all of which significantly benefit from the way quagsire has made a lot of setup sweepers a lot worse.
Previously stall wasn't so scary because of how badly things like NP Mime hurt it, now you have to beat quag with really strong hitters (mostly CB/specs things if not SE coverage) rather than setup sweepers and that hurts you vs the rest of stall. And maybe people can adapt and start slapping HP grass on more things, but for now it's hard to say that quag isn't an incredibly limiting mon based off of what you can and cannot run simply because it's in the tier.
And I'm sure people who dont want to ban quag just read that as "blah blah blah he can't adapt or run new shit" because of the way I went about explaining it, so tldr quag stall is very hard to beat and puts restrictions on builds in a meta where you already just couldn't account for everything so just because 1/4 of the mons in the tier can run toxic or hp grass for quagsire or because it itself isn't the strongest sweeper around doesn't mean that it doesn't hurt the tier.
Now I was fine with waiting to look at the meta a bit because there's definitely a chance that we do find some incredible ways to beat quag stall and still have just enough space to prep for everything else. Nothing I've seen in the over a month quag has been around has suggested this, but sure that's not impossible. Just pretty unlikely that we all wake up one day and realize beating stall and not fucking yourself over vs everything else is as easy as doing xyz changes. And with that in mind I absolutely hate the mindset in this post.
Without writing too much, because a lot has already been said.
I think that quag on its own is not broken at all. As explained, the amount of coverage options that people are just ignoring because they are either using teams that are old or ignoring the fact that quag is very limited in what sets it can run. Unaware + curse is very good when facing setup sweepers such as duosion / clef / bouff / pawniard, but it's literally the only thing going for quag.
Quagsire itself the pokemon is not the issue. What it provides to stall teams and how it hurts so many mons in the metagame is. Unaware+Curse might be all it has going for it (yes that is most of what it has going for it although as we branch out and find new ways to break quag like you and galbia predict I dont see why it can't start finding new sets too), but why does it need to have anything else going when it's how it changes the meta that's important.
The weaknesses it has - such as grass types (leafeon, roselia, servine, quiladin) or just grass coverage such as hp grass on zeb / floatzel (which really aren't bad options at all) make it very easy to lure. But the biggest thing is its vulnerability to toxic / status. It has a huge number of checks such as altaria / lumineon / prinplup / bronzor - plus literally anything that can carry toxic. It means that quag needs heavy support and there are many ways around beating it.
Do prinplup/bronzor beat it without carrying toxic? I'm p sure Prinplup would just get set up on and yeah zor can PP stall I guess assuming they never start running waterfall but that's not really ideal. Anyway, the hey look it's 4x weak to grass argument is one that we've already had to respond to multiple times because it's the first thing pretty much anybody says about this mon. Hey look just lure it with random grass shit. In practice I don't think it's proved to be quite that easy because with or without random grass coverage on, idk floatzel, quagsire is still going to do its job of shutting down boosting Monferno, Muk, Pawniard, Mawile, Bouffalant, Drifblim, physical huntail, etc. And yes, I do think the hurt it puts onto SD sweepers has a significant impact on the metagame. This didn't have to be a negative impact, I'm not saying all change is bad, but in this case I think it is for all the reasons pro-ban people have previously stated + the above portion of this post. Quag might have a good amount of checks, but it also has a good amount of top mons checked by it, and that's huge.
(oh and also toxic weak isn't the end of the world when stall has a reliable heal bell user, it helps but it's not like one toxic and you've invalidated its usefulness)
Without looking at what it does just as a physical wall - it can also beat things such as weak boosters who have special attacks - namely false mentioned duosion + clef. Well without being too obvious about this - both mons have coverage options available whereby they could EASILY beat quag if they chose to run a different coverage option available to beat quag. I'm not talking specifically energy ball / grass knot (which could also hit golem), but also cm + toxic being an option. It's not hard to think of things.
Actually I think it is hard to think of things for some mons. Sure, you can pick the ones that can learn energy ball and only have a moderate opportunity cost from losing out on hugely important moves in twave/knock/encore and acid armor/HP fighting/signal beam, but I can just go back over to the list o' things that dont have convenient grass coverage like Bouffalant or whatever (unrelated but taunt toxic comeback pls).
As for response - I believe that, unlike previous times, the only time people will be playing PU now is to prepare for LTPL, which half the time teams have been recycling old teams from PU open (Namely Blunder using my team that i built near enough 5 months ago - how the fuck did he even get it i don't know) in the first weeks of pu open and in general teams being lazy with their builds. Secondly, because there is a massive lack of people playing PU right now, the adaption to quag has been more than slow - hence teams who have developed faster than others (namely kinglax's in pupl with me and hjad, or dundies' stall team as he was prepping and building for pu ssnl) - the teams that have adapted faster have better results. I think it just takes longer for others to adapt because there are less tournaments, less opportunities to play pu competitively, less adaption.
There's less competitive play with updated teams but there is still some competitive play with updated teams and when a large amount of people engaging in said competitive play have pointed out an issue for said competitive play why would we not pay attention to the warning signs at least a little bit because "there's not enough serious people"
Hence this leads me to the conclusion that because of people adapting very slowly - I think we definitely need more time to even consider the proposal of a quag suspect because it on its own is very beatable. Also - when something goes up on the suspect block - it is more than often considered broken - hence would be likely banned, hence I would want to avoid this unless I was genuinely divided 50/50, however from playing and adapting myself, i am 100% convinced that quag is not broken and deserves to stay in PU.
When I said I hate the mindset in this post, this is the part. "We need more time to see all the facts but I'm convinced it's 100% not broken so I won't change how I'd vote anyway"????? Regardless of who time and adaptation proves wrong there's no way you should be able to justify these two statements together. Also we've had over a month, multiple tournaments, plenty of good players coming forward about this, how is that not enough to "consider the proposal" even if we don't actually do anything? This part might've just been poorly phrased though, because literally all hjad's/dundies's/galbia's/your/my posts are doing is considering the proposal.
tl;dr quag is not broken, it has plenty of checks, answers and ways to beat it, adaption has been incredibly slow because dead tier and only 1 pu tour left, once it goes up on the suspect block people will perceive it as broken before having time to get a full idea of how it is in pu fully. Hence wait longer to adapt more - ideally maybe another 2-3 weeks.
And ultimately this is coming down to "there are lots of ways to beat quag". And I understand, it's far easier to think about that than make a completely subjective judgement on whether or not quag is "unhealthy". And any time a mon is being banned because it's "unhealthy" and not broken it's a lot more contentious because of how subjective that is and I can understand if you see that side and then decide nope, quag's still fine for the tier to handle. But I think you've simultaneously overrated how easy it is for a team to deal with combined with how restrictive it is to need to deal with quagsire.
And for the record I've been sorta high on painkillers while doing this, not using that as an excuse to not take what I'm saying seriously but if there's anything that looks disastrously wrong just let me know and I might've really overrated how I think about some topic or another. The main point all looks fine though
