MK I am neutral about. Might sound weird coming from the guy who made the planking info thread that showed MK was broken with planking, BUT it's true. Basically here's how I see it:
MK, as he is, is too strong to be allowed without at least some kind of restriction on him. While I think the idea of a restriction on him, or anyone in the first place is MEH because it suggests "Hey this character is stupid, but our community won't admit it so we just cover it up with rules", but honestly I think that situation of having a "bad" rule is better than having none at all. I feel that the easiest and arguably best solution is to ban him, but I could respect the community if they decided that limiting him was the best solution, and took action.
