The nerfs yasuo needs, not the ones everyone thinks he deserves

The 3 things he needs to have happen are:
-
When he windwalls it uses up his flow bar and it lasts for an appropriate amount of time based on how much flow was used. 1-3 secs. This makes him have to think on when he uses it and it gives his opponents counterplay to the windwall (besides moving through it) by popping his shield prior to it. It was always meant to be a reactionary measure and this makes it more so.
-
Windwall's passive numbers need nerfing. The ones they used for a while back on pbe were good. This gives more counterplay to his shield by increasing it's downtime when it gets popped.
-
A slight change to his shield amount earlier on but keeping the final one. To keep in touch with the original idea of him having a weak early game.
current:
60/65/70/75/85/95/110/125/145/170/200/240/290/350/420/500/590/690
proposed:
50/55/60/65/80/95/110/125/145/170/200/240/290/350/420/500/590/690
As you can see it hits his early game by making him a little squishier, but not so much that he can be sneezed on and dies.
Everything else on his kit is fine, I love his synergy, and how he utilizes teamwork so efficiently.
