@Riot Yasuo is way to mobile and strong.
I know this champion is supposed to be extremely mobile and in your face. The problem is that he can spam everything, has a w that blocks everything in front of him, Yasuo can spam his dash attack, he has a double crit with his passive . . . . and your only response is that the wind wall is working as intended and you are "looking" into making his crit passive so it scales with his level. Again, like everyone has told you, this champion is too strong. You need to remove her crit passive and put in a ability or just remove it period. His windwall is ridiculous since he can block all projectiles and ultmates. Like no one can even attempt to make a play on this champion since he can practically spam his W. What I don't understand is that Fiora has something very similar where she can block all damage and what not. For the most part I think it is pretty balanced and it has a long cooldown. Yet we have a Yasuo that can spam his W every chance he gets. Drastically up the cooldown of that annoying ability or completely remove it. It's ridiculous.
Sometimes I wonder if you test anything at all. You claim to be aware of all the problems but it seems like you are not tackling the issues. The main issues with Yasuo is his double crit passive or w/e and his windwall. Fix him please and listen to the community.
