My problem:
1) Everyone who says MK dominates the metagame is completely ignorant.
MK has disadvantages. Bowser and Yoshi can now play on much fairer grounds due to new strategies like grab release chains, he is a light character so killing him should not be as hard as people make it out to be. The people playing MK are human, ergo make mistakes. Punish them and get an early kill due to his light weight. Because of his dominance essentially every character has to develop anti-MK strategies. Read character boards and you will be surprised on some of the viable options.
First: Don't generalize by insulting everyone and labeling them ignorant.
Now, to rip apart your flawed post.
Bowser and Yoshi have chaingrabs on Metaknight. Yes.
Metaknight's entire moveset dominates Bowser and Yoshi in every single other aspect of the game. Speed, ground moveset, air moveset, air control, priority...these characters are utterly dominated by MK.
The grab alone is not enough to make it an advantageous or even an even matchup against them. Especially when you consider that MK is one of the hardest characters in the game to grab, and isn't disadvantaged by remaining in the air, and the grab is not a low percentage auto kill.
Until this is proven in real life- i.e., a high level bowser player or Yoshi player beating a high level MK, such as Dojo, Plank, DSF, Mew2King, or Azen- then it is nothing more than wishful thinking.
Consider the following. The best player in WA, Bladewise, mains Marth, but he switches to Bowser when facing a Metaknight and goes pretty even with Eggz. It's worth mentioning that MK is almost soft-banned in WA- only three good players use him, and then there's a ton of MK scrubs. The three good players are Jem, Eggz, and brdy- and Eggz is switching to Dedede because he doesn't like the stigma associated with maining MK in WA. Jem just goes around insulting everyone who doesn't like MK.
Now Bladewise went to Axis and fought DSF's MK with his Bowser.
He got three stocked, and DSF had
no Bowser matchup knowledge.
The CG doesn't give Bowser enough of an advantage. He's still disadvantaged, just not as much as the rest of the cast.
2) Matchup charts are flawed. Don't rely on them.
Just because you read a general all character matchup chart and it said MK beats Snake, don't trust this. Snake still retains field control, MK has issues dealing with grenades, really early U-tilt kills, etc
The matchup chart IS flawed, but nobody here is relying on it. The strongest argument for MK having the advantage on Snake slightly is the fact that the best MK's are consistently beating the best Snakes.
Even M2K agrees that MK has issues with top level Olimars. And let me guess, "MK ***** Olimar, his recovery sucks." Again look at the Olimar boards, he has a lot of options to solve any problem he has. Have you tried to gimp an Olimar only to have him use his whistle to go through your attack and spike you and tether back? I've done it!
Characters can do more than most of us think.
Not enough to allow the best Olimars to actually beat MK's, once again.
3) How many of MK's matchups are a 60/40 in his favor? I think we can agree that a 60/40 is not an instant loss. In theory you know your character better than the MK does, so just make sure to know equally as much about what MK can do to you. Knowledge is power and can turn a 60/40 around in your favor.
MK's worst matchup is another MK. His next worst matchups, Snake and Diddy, are 45:55 MK's favor. He's got 60:40 on a large majority of the cast. This BREAKS the counterpicking system.
4) How to break a game: Other characters have absolutely no options against you. You dominate the game no matter what. You beat players that are better in skill just because you use this character. The metagame revolves purely around you.
I don't think MK fits ANY of these categories. The pure fact that MK has neutral match ups goes against the first. There is solid proof of at top level play, other characters win. Top level players will **** you even if you play a decent local level MK. Don't even argue against that one. Smashboards are solid proof that the metagame does not revolve around MK.
MK's worst matchup is another MK. Other character's positioning in the tier list revolves around their ability to fight them. The metagame DOES revolve around him.
5) If we ban MK do other characters become viable?
No. We will see the other top tiers and high tiers win more often instead. Banning MK will not make Jigglypuff, Sonic, or any other way down there characters viable at top level play. I don't know exactly but I can almost guarantee at least one other character in the high or top tiers take out these characters just as hard as MK or potentially harder. Every other character will just remain at that potential maybe if the best person at the tourney is using said character.
What about ROB, who does very well against most of the top tier but can't place because MK has a ridiculous matchup against him? What about Mario and Luigi, who also can't do anything in tournaments because of ridiculously bad MK matchups? What about Peach, who does well against the high tier except MK and G&W who destroy her? What about Toon Link, who does extremely well against the high tier?
MK's removal means it won't just be the few characters with decent MK matchups that place well next to him.
6) Even if MK is banned here, the rules the SBR create are a RECOMMENDATION.
Is every single TO out there going to ban a character that can legitimately be beaten?
Unless the TO is a complete idiot, I doubt it.
You're implying that the SBR are complete idiots?
