I havent heard of a really dominant sheik in any particular scene eitherAlso, The 5S I think is Sheik, Samus sucks and I've never really heard of a dominant sonic tournament scene, at least locally or in tournament videos.
also, not trying to start a fight here, but out in Utah theres this guy named X, and I dont think hes placed lower than third in close to a year now, and he mains sonic. So theres at least one area that has a dominant sonic, for what its worth...
