do all the talking since he's saying everything I'm thinking already.
Well except for this. A big thing that I'm seeing argued is how we should 'ban' miis from using their expanded moves in standard play. But to ban something, it would have to be legal in the first place. I'm far from up to date, but I don't believe any major tournament has allowed them outside of the 1111 set. We're not arguing to ban, YOU guys are arguing to make legal.
This (I hope) should help your perspective on the situation some. This is not people ganging up on poor mii mains trying to make them worse, its everyone else in the game saying 'hey I dunno about letting that one character just get better for no reason'. Yes, it would make all you guys happy but don't forget that would be a slap in the face to every single other character main.
Move for move, 1111 mii brawler is at no inherent disadvantage to any other character in the game. You have just as many special moves as anyone else. You have all the same aerials. Tilts? Oh bb you better believe you got those too. You don't have to LIKE the default set, just like a DK player probably doesn't like the 1111 DK as much as customs. If you've got a problem with that, then push to make customs legal, don't try to artificially get a leg up to make your character work.
