3 ways I would nerf Yasuo

I've just play a game as Yasuo recently went 21/9/12 and he's pretty fun to play but I sure as hell know he's not fun to play against. I think the problem is mostly Yasuo's E you can engage with it disengage with reposition to dodge abilities and each dash increases the next dash damage by 25% for 5 seconds up to 50%

First, his windwall, although the ability can be quite annoying it has a solid cooldown. Basically I think Yasuo should be able to be hit from the rear of his windwall it you manage to reposition behind him. One last thing, it should'nt be about to block the return of Ahri's or Ekko's Q on the way back if he's facing the opposite direction.

Second, his ultimate Last Breath it needs a longer cooldown. The cooldown is too short at the moment 80 / 55 / 30 it should be increased 80>100/55>75/30>50

Lasty, the his E(Sweeping Blade), This is kind of complicated but I'll try to explain it the best I can. Yasuo should have a cap on the amount of times he can dash to minions. With level 1-2 of this ability yasuo can dash only up to 3 times after that it's set on a 3 second cooldown before he can dash again. With level 3-4 of this ability yasuo can dash only up to 5 times, after it's set on a 3 second cooldown. With level 5 of this ability yasuo can dash up to 8 times maximum with this ability and after it set to a 3 seconds cooldown. I believe this will stop Yasuo from constantly harassing you then backing away now he'll have to commit then wait 3 seconds to get out, this will allow ranged characters a window of oppertunity to attack. Yasuo won't be able to easily escape ganks anymore and he won't be able to do the level 1 cheese on ranged characters anymore: https://www.youtube.com/watch?v=Eu2wRiWtRvQ https://www.youtube.com/watch?v=46QCU05OxwA

But at the end of the day Yasuo will still have his damage. Do you disagree with my changes? are they too much? is there something you would change? Let me know below in the comments :D (And actually give explanations instead of "bad idea lolz downvote")
