only reason why yasuo is a problem in my eyes.
i don't think yasuo is OP, i don't think he needs nerfs. But the reason he is problematic is because of windwall and thats it.
i destroy yasuo players in my elo or go even with them all the time, the problem comes mid to late game where he can drop a windwall in the middle of a team fight and invalidate people for a couple of seconds and there is nothing you can do about it. its a giant black hole that completely removes anything projectile from the game with a few exceptions.
they need to rework that ability, because no matter how well you play at some point all yasuo has to do is press W and remove any projectile based character from the fight for a couple of seconds.
