The problem is the cold community has quite literally said the words unviable, can't top 8, tons of 7-3s (or worse), no neutral, no mixups, only in the corner, only against rush down, bottom 5, etc to define the character. Yet Sonic didn't just eek out some wins with gimmicks, he spanked some of the best, including people he probably plays all the time without breaking a sweat.
If everyone who mains someone better is supposed to be realistic about their character, I think that requires a little more accountability than sonic is just better than us.
