.You realize that until brawl has a new style of movement, Metaknight is AT HIS PRIME, right? There is NOTHING else to add, it's all up to the brain now. Shuttle Loop, Spacing Aerials, "mindgames" (I put quotes because a lot of people use various definitions of it). He can't do anything else until there is a new style of movement in Brawl.
.Marth was winning nearly every (major?) Melee tournament from late 06 until Brawl was released, and Marth was NEVER being considered to be banned. Don't try to tell me he has several bad matchups in melee, HE DOESNT.
.Most Metaknight's are really dumb players. The only smart Metaknight's I know are DSF, Eggz, and myself. Everyone else just constantly spams smash attacks. And if you can't beat that, then you're a bad player yourself. And if you can't beat that, might as well ban GnW too for the same reason.
.The Metaknight's winning tournaments are playing REALLY smart. Is that a crime? This once again goes back to how DSF, Eggz, Myself, and M2K play as smart MK's. People are saying "if I'm as smart (can't even happen anyways, there is no tie game in smarts) as the metaknight, I should be able to win." No, this goes back to matchup problems. This happens in ALL games, even sports. You need to play BETTER and be SMARTER if you're in a disadvantageous matchup.
.Metaknight isn't dominating every region. Azen mains Lucario, but plays MK as an alt. He doesn't main MK, so don't give me that garbage. Lucario can't cover all his bad matchups so he feels its the better thing to do. Oregon's best players and winners aren't Metaknights, Nevada's best player is a Falco, you can even argue WA's best player (in your opinion, that is, if you feel Bladewise is best in WA) isn't a Metaknight.
.Metaknight isn't as perfect as you guys make it out to be. You can beat Metaknight with Falco, Snake, Game And Watch, Toon Link, Marth, DeDeDe (If you don't believe me on D3, watch Eggz d3 **** most the local MK's with him).
tldr version: GET SMARTER. PLAY SMARTER. HE ISN'T PERFECT.
