I'm a firm believer of nerfing Yasuo
But you can't make his windwall cost flow. It would destroy his kit and he would never be able to cast it.
Stop just upvoting people because you hate Yasuo and his windwall.
If you want to nerf Yasuo and his windwall can actually care about balance in the game I feel like nerfing his windwall in different ways is better.
The problem with Yasuo isn't that his wall eats a ton of projectiles (once its up stuff only hits if he dances from side to side in it or you misjudge your angle). The real problem with Yasuo's windwall is that Yasuo could just completely throw it backwards and block something coming from in front of him because the windwall itself is an instant projectile the floats forward. How to fix this. Make it have a .25-3s cast time and have it appear at max range instantly with no drifting of the wall. And if that still isn't enough to fix the problem then you make it slightly thinner on the hit box.
Now Yasuo may not be the biggest threat now with the bug fix, but it still doesn't solve his inherent problems and the reason his kit is never allowed to be good. His kit is cancer. Let's be honest. And the reason it's cancer is how much free stuff he gets for very little risk. I mean seriously he is less risky than 
and does higher DPS, is stickier, and has potential CC on top of needing less gold. In order to fix that you have to slowly trim away at his utilities and make him more focused on what his kit supposed to be about.
For an example, I am trying to fix this shit
