How to fix Wind Wall
Make it so the windwall doesn't move forward after moving slightly in front of Yasuo. That way, all the ADC's and other people have to do is back up a little bit in order to start attacking Yasuo again (Yasuo is melee and will have to follow if he's using it aggressively).
This will make the ability more about defense rather than throwing it into the ADC's face when you're right next to him.
