Yasuo's Windwall

Yasuo is like that fan favorite champ and he's been around so long his concept is hard to balance. I get it. But that WINDWALL tho. Shouldn't there be like a limit to the size of the type of projectile he can block with it? the wall comes out near instantly while blocking near half the lane come late game. If not a projectile size limit then a projectile limit??? Like it can block multiple ults, regular spells, just entire burst and all he has to do is just point it in the right direction. you can try to wait it out to see if he'll t preemptively try to block something but most reasonable yas players wont do that. It just feels like a massive reward for doing...not so much...feel free to disagree.
