As a Goro main, and top Goro player on PC ranked, I can safely say that Goro is mid tier at best. MAYBE top 16, but just barely, at probably number 16 if he's lucky.
I don't even get how people could argue that Goro doesn't need a 50/50. All characters do, otherwise you get what we have now, all the top characters have 50/50 and all the trash tier ones don't.
As much as Love him, Goro is just a twitch gimmick character. You win by anticipating your opponent, but if you mess up once, you get caught up in a 40% combo 50/50 vortex blender and if you don't have EX, you're done. Heck, even if you EX Punch walk out of a vortex, you just walk across the screen like an idiot, and the opponent can just vortex you back up anyway.
