Consider the following half unpopular-opinion, half chiming in on PLA.
I frequently find the Pokemon main games to be incredibly boring because it's almost entirely Single-Battle OHKO focused, which is something that affects the entries I like as much as the ones I don't. I get being able to clear out Wild Encounters or obvious Fodder trainers in very short order, but even a lot of the bosses tend to play out as "one-shot their Pokemon and move along". A lot of RPGs I play can have this issue in places, but Pokemon is where I notice it most frequently and, in my opinion, to its detriment. It leads to Pokemon without stand out offenses being a borderline impossible sell for the in-game runs, and also means most of the battles are lopsided difficulty wise if you understand the most basic game mechanics of type match ups and aren't specifically handicapped (like using all Special moves on a Phys-only Pokemon like Ursaring).
The thing that has me most interested in PLA so far is the talk about how building teams with a balance of offensive and defensive backbone seems to be very important to handling a lot of the harder battles. I also very much enjoyed the Orre games because there was more cause to consider Pokemon with supportive effects or defensive utility (be it natural or Shadow vs. Shadow in XD's case) to not only deal with Pokemon who were often stronger than your team, but employed legitimately disruptive strategies like Miror B's bulky Rain Dance/Dish Ludicolos, or Ein's Rain and Water/Thunder spam team. Given the number of trainers was a bit sparser relative to the number of bosses, considering who to level and how your team worked together was a lot more important since there were more Participants per battle to manage and you wouldn't (easily) outlevel and simply overpower opponents the same way.
I notice that the way most other RPG's go, they either incentivize learning a bit more about the Battle System (if only on the level of balancing offense and support/defense to a party for the long haul) or compensate the simplistic battle experience with other elements such as variety of content, story, etc. Pokemon sometimes dealt in the latter with extras such as Gen 4's Underground or Pokeathlon, Gen 5's PWT and greater investment in the story elements, Gen 7's Mantine Surf, but it's not necessarily consistent enough that it manages to compensate on a level that lets me gloss over it like in Final Fantasy for example.
tl;dr I'd like Pokemon to step outside the Single-Battle One-shot fest, whether with existing systems like Orre's Double Battles or innovating on it like PLA did with the Style System/Encounters/Move Overhauls
