What Yuna says does have logical basis though. In my opinion, Yuna is correct. However, now thanks to these posts, I really understand why people want to ban MK, and it's reasonable to a point.
Really, that's probably all it comes down to. If people want to ban MK, ban him. If it's for the sake of funner competition, then so be it. IMO, it IS sort of a scrub thing to do... but hey, it's fun, right?
MK doesn't deserve a ban for being too good or being advantageous on every character. He is the best character, yes, but he can be beaten because he has even matchups. He doesn't deserve a ban at all. But if people ban him so the competition is more enjoyable, so be it.
IMO, MLG, MD/VA, and Cali will never ban Metaknight because at the highest levels, it's really about competition.
