Like I'm 
and put an e diagonally to where there is supposed to be an opening and it still fizzles out. Yea one lone pixel probably caused that, but still, some abilites like velkoz e feel like they shouldn't be blocked by windwall yet still are.
His E being blocked makes sense. If you pay attention you will notice that Vel actually shoots a particle to the E target location to generate the E knockup, so that particle would naturally be destroyed by the windwall.
It is Vel's W being blocked by windwall that makes less sense (unless they have changed that interaction).
What i don't understand is if Yasuo is standing on your w and is ht by the first part then remains on the rift and wind walls the second burst doesnt do any damage or proc the passive stack even though it does its damage at every area at once and that isnt projectile behaviour
