What if Yasuo's windwall blocked ally projectiles too?
I don't think he's op right now (he's just been nerfed, after all, so it's too soon to tell), but I do think his windwall is frustrating to play against.
With it, he can protect his whole team and effectively turn enemy ranged champions into target practice mannequins.
As far as I know, slayers (melee carries) are meant to... slay the enemy team, not protect their whole own one.
If it blocked ally projectiles too it would be more like 
's wall and less like 
's: still useful, but if used badly or randomly it could screw your own team instead of it going on CD being the only punishment you get.
We have even ultimates that can screw your own team, for crying out loud (looking at you, 
and 
and 
and etc)... a base skill with such tremendous utility getting a downside shouldn't be a terrible scandal.
This doesn't have to be a nerf: you could switch some power onto the rest of his kit, if needed.
