Yasuo changes that could easily make him less toxic to play against, but not gut him.
Yasuo is really, REALLY anoying to play against IMO, but I feel like these changes could still keep his identity in tact woithout just gutting him completely.
2 things are core to Yasuos kit, his Q, and his R.
His Q is the ability that makes it so his R is not ipossible to use and goes along with hi 3 strike idea, and his R synergises really well with champions like 
However, his E and his passive are abilities that I feel are the issue on Yasuo. 1: His E allows for easy escapes and or chases, especially in lane, however removing his E wold also destroy his kit. 2 things can/ should be done to help fix this issue.
* The first would be to either remove his damage on E or make it physical damage, this would allow building armor as a real way to take less damage from him. Magic damage on his E just lets him use E as a fallback source of damage in trades against armor only enemies,
* The second idea would be to make his E up less often. By this I mean make it so it has a .5 second cooldown only if one of 2 things happen, he kills a minion/ moster OR uses the ability on an enemy champion. This makes using miniions as a 1500 unit dash less viable, otherwise he has a 2 or 3 seond cooldown on his E. This allows for high level players to be able to use E on low minions effectively while punishing players who use it greedily. This also means that he can't use random mosters/minions so easily and recklessly w/o punishment.
2: his passive provides him with a near infinite shield that can be recharged quickly, the easiest fox for this would be to make it not charge when he uses his E and provide enemies and Yasuo with an indicator of how much hp the shield will provide.make the shield a darker gray than normal shield to give information that it is his passive and can dissapear when proced.
I feel like both of these changes to his kit would make Yasuo a lot less toxic to face while still keeping his identity in tact. What do you think?
(P.S. also remove his armor pen from his R?)
(P.P.S. I just came off of a game facing him as Orianna and do not like him at all, mainly his windwall stopping any command movement I do tilts me. "Oh, my teamate needs a shield! presses E "FACE THE WIND!" ball magically disappears and returns to Ori using the mana and not giving a shield")
