Option 3
I enjoy the current metagame and see no reason to make a major change to it. As some users have pointed out it isn't very friendly to stall, but it is never going to be in a metagame where every offensive pokemon has access to their strongest STAB moves. I do not feel that set-up moves are a problem and detract from the game, with the exception of Belly Drum which I feel warrants its own suspect, but it is a bad decision to vote to ban every boosting move just to get rid of one. I feel the current metagame is fine as it is bar one or two pokemon and Belly Drum. Sorry for the short reasoning but I am tired and just got back from a long trip.
