A lot of M2K's losses stem from him not having sufficient matchup experience/not knowing what to do. Look at his post about Diddy for example. He himself isn't confident in that matchup, and he still wins more than he loses against that character.
Take Fiction/Reflex too. Fiction/Reflex beat him not just because they were good, but because M2K underestimated what Wario was capable of and played too aggressively/incorrectly. Hell, I can tell just playing against M2K that he's still kinda learning that matchup although he has gotten a lot better at it compared to when he played Fiction.
IC's, hell M2K ***** IC's nowadays. He said screw it, I'm gonna camp really hard like I'm supposed to do, get inside when they mess up, **** Nana, rinse and repeat. People despise him for gliding under the stage, but hey all M2K is doing is playing to win. It's like people point out when he loses, and then when he tries something smart people tell him "Hey, that's gay, you can't do that." IDC is one thing, but you can't point out M2K losing to someone as proof that MK isn't that good AND THEN TURN AROUND and tell him "You can't play gay like that, it's too much, we don't want you to do that." If he's playing so gay that you have to prevent what he is doing, chances are his character is freakin amazing/a little ******** lol.
Also if you guys want, I can explain why you cannot believe Snake is the best character in the game, while also advocating for a ledge grab limit/gliding rules/etc.
