K, but even then I'm not exactly a fan of people ****-talking Seibrik or any other player for having to "actually put work" (generally speaking) into winning without MK, especially the **** EmoWolf was talking on 8-Bit's account in the live stream during grand finals. You do know Seibrik didn't win tournies right off the bat when he started using MK? CO18 took two or so sets off of him then. This discrimination against MK players in general is absolutely baffling.
Chops and Redhalberd are basically right, if Seibrik had as much Snake exp as he had with MK, the "3-0" you mentioned would more likely happen, albeit they'd actually have to work harder since MK is better overall than Snake.
