It'll take a while for people to realize how much better he is now. If they're putting him there solely for his weight, then they're just stupid. Oh well, GameFAQs is mostly a cesspool anyway.
I say he's low mid at worst and high mid at best right now. I think he has too many good qualities to be considered low tier. Fast mobility, excellent aerials, excellent recovery, great projectile, good throw game, strong finishers, and nice combos.
Weaknesses are tall frame, low weight, poor grab, and mediocre frame data. I think he has far more pros than cons.
