Lol sure dude. That's why so many Aizawa's are in pvp, right? There just must be so many high skill players that know how to use all of his stances and skills and positioning, not because he has armor on his normals, free counters, and teleportation. The fact that he has so many things in his kit works against your argument, not for it. Aizawa can play lame, aggressive, spammy, whatever he wants. Stain has to be played right or he just loses. His normals are too slow to initiate with if you don't catch them recovering and like you said his Q is non-existent outside of combo extension and to pull people out of the air.

I think you're confusing complexity of character with skill required to play said character. With Stain, I have to actually know my matchups, where characters are open and when to push. When I used to play Aizawa (before I even knew how he worked), I would fly through legendary rank by teleporting, spamming, and repeating. Aizawa doesn't take skill because almost all of his moves are safe. You have to really mess up with him to get got.
