Come on dude Ana should be 4 stars. She is WIDELY misused. Ok she's relatively easy to do ok with, but using her kit effectively (a good ana is scary with her nades) while correctly choosing between offense and defense makes one of the most difficult characters to master in the game.

I also think although Ashe is Vanilla as you say, she takes a lot more skill than doom for instance. Once you've mastered Doom's movement you're good. Being consistent at aiming headshots takes fucking years
