If you agree that to beat MK you have to play as MK, therefore the game will eventually devolve into MK vs MK, then you've pretty much found out why pro-ban wants MK gone.Then play MK.
Pit's planking can be dealt with, and so can his gliding under the stage. However, if Pit scrooges everytime the opponent starts making way towards him in order to avoid all contact except that of his projectiles against the opponent, I'm supposed to be able to call foul on that, because me catching up to Pit is impossible unless I use someone who does it better than Pit (MK is the only other option).
EDIT: Anyway, instead of continuing to talk about MK, let's change the topic. MK already has his own topic (which is huge, spanning over 100 pages of 40-posts-per-page), so that's the place we should talk about him and how he's too good.
