Yasuo Wind Wall - Reworked
Bear with me, okay?
Wind wall no longer creates a solid wall that lasts for X seconds.
The ability is now named something like Hew Projectile or Fell Wind. Upon casting Yasuo slashes the air in the area cast and knocks out any projectile that it contacts (but no wall is left).
The cooldown could be slightly lower. This would mean that the player must time their slash just as the projectile comes close. Too early and he will miss thus rewarding keen reflexes.
