WARNING IF YOU ARE A CASUAL BRAWLER THE YOU CAN BE QUIET THIS DOES NOT CONCERN YOU AND YOU WOULDN'T UNDERSTAND THE REASONS BEHIND BANNING HIM UNLESS YOU SAW HIS BROKENESS IN ACTION. With that being said I know meta knight is already probibly going to be banned. Now to start off I'lllist the three biggest reasons to bann meta knight.
1. HE has no bad disadvantage against any other character- Its true some character just beat others because of movesets. This is why I find tiers crap. Because these make much more sense and are have much more logic. So... what happens when you have ness vs marth marth has a longer range when face to face and is faster. So ness can't run away andmarth has an advantage. Not to say different stradegys also counter those but ignoring that... META HAS NO BAD ADVANTAGE. The worst sidadvantage he has with himself. EVERY OTHER CHARACTER has a dissadvantage when fighting him... TELL ME THATS NOT CHEAP.
2. HE ruins the metagame (get it)- Alright despite the terrible joke I just pulled... the metagame is when someone is pwning in tourneys. Snake was doing this before meta and he has an ideal example. Snake was pwning in brawl and people thought... "HEY let's ifnd counters for snake and beat him down"!!. Yes that explains it much better. So people use D3 and Meta Knight to beat him. Meta gets top and never goes down. Actually people are using meta more and more. The variety of characters and counters because he has no counters. Let me ask you this, Why would you play as a Character who has bad matchups when you can play as someone who has no bad matchups. He is over populating tourneys more and more.
3. His recovery is BROKEN, BROKEN, BROKEN!!!!- Alright perhaps the least important reason heree but still a danm imporant reason. Lets say you edgeguard. If you don't know what that is (it means your a casualplayer and you shouldn't still be here). Its when you are on the edgeso he can't make it. MK and pit can actually use their broken recovery to make it to the other side to give a big old punch is the face to the other guy. The difference is pit only has umm... one way he can do this. MEta has about 20 different ways >_> That and its unpredictable is unfair. Those are my 3 reasons.
