When did Yasuo Q mid ult?
Why should Q not proc anything? That makes no sense, it already does less damage than an auto attack late game. What the fuck is the point of that? It fits no place on Yasuo if it did not proc anything.
Yasuo can't cast his own ult without having to land a knockup, which is even harder to do know with the slow speed and cast time + the recent nerfs, why can't he be allowed to do that?
So now you don't want him to be able to fight tanks? He's a skirmisher.
All of these are questionable, to be honest. His ultimate has no massive damage unless he gets IE, PD and BT mid game and has full stack fervor. His ultimate isn't even close to Lee's damage. The only nerfs he can receive will get him buffed straight after because unless Riot want's his winrate to go below 49%, he's getting buffed. And these nerfs will literally make Riot serve him steroids.
Also that's 4 things not 3.
