If everyone would switch to Falco/Diddy/Snake/ICs/Marth/Wario/ZSS we could stop complaining about MK.
But if MK is banned, then that character range expands to include Luigi/Lucario/DK/Peach/Sonic/GaW/Pikachu/ROB/Kirby.
If people would have a melee mentality and accept that MK ***** most of the cast and while he still beats other good characters they have a much more legit chance, then I would say there's no reason to support a ban (unless results STILL looked like Pound4). But as long as people want to play other "decent" characters that only really suck because of MK, then people will complain, and part of the community will support a ban. I'm not calling either side scrubs, I'm saying that people play this game for different reasons.
You say "well if you don't like MK, and wont pick up a better character, then quit"...well ****, there goes half the community, half of tournament attendance, and Brawl as a competitive game dies.
That's why we have to work to please the majority. Because otherwise the community dies either way...
