Taylor, those are all cases of the players just being better than the MKs (or the MKs being bad at a matchup)
There isnt one matchup in this game to where if the MK takes full advantage of his character, then he would lose. He literally wins every single matchup. And they arent even close to even like some people think. ALot of people see a top MK lose to a top ____ and automatically think that character beats or is close to MK. No it doesnt work like that, the person playing the MK has his own shortcomings. The character MK is still broken, but alot of people at this time don't know how to use him fully, or plainly arent as good as their opponent, in which case it wouldnt matter what character either person is playing
Looking just at the character, not at the people playing him, MK is broken. HE does a long list of things that no other character can do at all (some can do but with about 50% efficiency as him). I think the problem is that because there arent enough MKs around that take advantage of their character completely, people tend to think player miscomings equals that the character itself isnt that bad.
But whatever, its not even a debate, its an argument. Neither side is going to budge so I'll just have to deal with it until smash 4 comes out
