I looked at the videos and I was so leaning towards "ban" and then a few funny thoughts occurred to me after I got a drink so this might be a bit messed up...
(Warning, kind of rant-like):
I voted "no." The reason: I don't think it should be done permanently without some sort of testing first. If anything, if it's that dire of a situation, a softban or temporary ban should be placed on Meta Knight for a few months to see the results. I don't see why this cannot be done, because it would be the best way of ending this whole MK fiasco. If there were more "Meta Knightless" tournaments that showed variety (or at least a larger variety) of participating characters IN ADDITION to variety of winners as a direct result of MK being removed, then I would be all for it. And no, I don't mean that with MK gone, suddenly Snake, D3 or Falco have more wins, I mean there is an obvious and honest to goodness change as a direct result of the removal of MK. Because as far as I'm concerned, even if Meta Knight were removed from the metagame, the only thing that would happen is that the other top tiers would absorb Meta Knight's wins. Which doesn't mean a thing. It doesn't fix the imbalance that runs rampant through the game (poor, poor Ganondorf). What I mean is, I don't think the removal of Meta Knight is suddenly going to make more people decide to use-- for a quick example-- Ike, or even start winning with him because Meta Knight is gone. I suppose my question is, what DO MK-banners expect to happen as a result of MK being gone? What's there to gain? I'm still not fully comprehending this.
Although admittedly, you'd have to be a fool to think that MK wasn't designed to be powerful, because everything about him just screams overpowered, and it IS. I just don't think that he's so excessively overpowered to the point that he's completely ruining the Meta-game. There isn't anything that proves he is. Not even the tournament results. We don't know if MK is winning because THOSE players are just that spectacular regardless of chosen character, or if it is directly because of Meta Knight. Yes, I realize that some people have claimed that they "win with Meta Knight without training," but hey, people lie in order to make themselves sound better. Not to mention, them playing 3 hours of Smash a day might not be something that they consider "heavy training." I know playing ONE hour of Smash is a lot for me for instance. Not to mention that some people might have actually mentally psyched themselves into believing that MK is more/less powerful than he really is at this point (perhaps some, but I wouldn't throw this possibility out).
I don't understand why people that main MK feel the need to quit because their favorite character got banned. Call it whining that people call for a ban for a character being *understandably* labeled "broken," but if he gets banned, quitting doesn't assist the situation. If he DID get banned and MK mains switched to other mains and still destroyed people in tournaments, that would be the easiest way to bring him back; proving that it was never MK that won the tournament, but the player's effort and diligence. Quitting would just leave a sour atmosphere and give pro-banners the right to smugly grin and state "I knew he/she was only good because of Meta Knight," and leave most people believing such a statement to be correct because the MK mains quit.
If anything was learned from all of this, it's that Meta Knight's existence confirms that pretty much all of the "veteran" (and some new) fighters need MASSIVE buffs and moveset tweaks/changes if they make a Smash 4 because Meta Knight is one of the few characters that seems like there was actual THOUGHT put into his moveset and how to make his moves not suck or highly situational... Unlike some OTHER characters (I'm sure most of you guys and gals can think of far more ideas than I could having played the game more extensively).
But what the heck do I know? I'm just a newb. X_X Go ahead and laugh at my ignorance.
