The WBR is full of experienced, long-time Brawl Plussers. As the project expands, one side effect is some new(b) people play the game without thinking much about the goal, but around the aspect that the characters in the game can be buffed/changed.
With SA, I'm just afraid people will go overboard, and we'll be flooded with request to change "useless moves" and such. There's always a possibility mains of a certain character will jump on the bandwagon (who wouldn't want a nice buff?) and other members of the Workshop will be eventually unable to argue their way out of such situations.
I guess I sound a bit paranoid, but better safe than sorry.
