DK is a completely viable character, it's just a single move that can infinite into itself that prevents that. There is no other character and no other move that makes DK an unviable character. Ganon is unviable for a multitude of reasons and DK does not have such limitations.
Stop using viable as standalone.
DK is viable if you get one character to take out his one matchup he's doomed to lose. That's not even a theorycraft thing. That's pretty much a fact right there.
He's also not a standalone character, but as far as that goes, tough break. You don't ban something so somebody can stand on his own two feet.
limited =/= completely prevent, stop trying to change my point and argue about something else. DK's metagame would undoubtedly advance much faster if people thought he could be used viably in tournaments without having to worry about a single broken tactic that kills his potential. DK's metagame is part of the metagame. No matter how many times you say that limiting DK's metagame doesn't limit the metagame still makes you wrong.
DDD's metagame is part of the metagame, banning this would limit DDD's metagame and thus limit the metagame.
Get. Better. Arguments.
And as for the stuff about DK, I was thinking of another "tough break" post, but it's not a tough break. Host a tournament with it banned. Play at tournaments with it banned. Go to areas where it's banned and play the character. There are places where this thing has pretty much no influence on how he can do in tournaments. If people don't want to play a character because he was one glaring flaw (as opposed to half of the cast's bazillion flaws), then they're stupid.
You're kidding yourself and everyone if you think that this is seriously holding DK back. Anyone decent and somewhat intelligent would know that this isn't the nail in the coffin for him. In fact, he's not even nailed in a coffin because he's still pretty lively despite the oh-so-terrible thing we're talking about here.
Saying it refutes and it actually refuting are two separate things.
HURDURR, WHUDATHUNK IT.
And yeah, it has been refuted already, check this thread and
all the others like it. If it were never refuted and made sense, this would be officially banned, but guess what, it isn't.
