There is a loading screen tip that says that Wind Wall does not block lasers, such as Lux's ultimate. Viktor's E (Death Ray) is a laser, yet it is blocked by Yasuo's Wind Wall. Why is this? A laser is not a "projectile."
LoL abilities that move from point a to point b, such as death ray or velkoz q, are coded as projectiles. Lux's R, is a aoe ability that hits everything in the area of effect at once. Another interesting instance is that wind wall cannot block the damage from vlad's q but does block the heal since it moves from the target to him.
Viktor's autohit after his Q does also go through the windwall... But it also goes from point A (Viktor) to point B (the target).
