So, Viktor's Death Ray...

Why is it considered a projectile by Yasuo's Wind Wall?

I was playing a game against Yasuo, and it happened multiple times against Wind Wall.

The moment my Death Ray's hitbox touched the Wind Wall, it cancelled the move.

Why? It's clearly an AoE, so why do these two abilities treat it as a projectile?

EDIT: Evidently, it's not just Death Ray, but Vel Koz's W and many other attacks that should CLEARLY be treated as an AoE.

I've gotten several messages explaining this, and I understand that this they are treated as projectiles because they have a travel time.

This may be how it works, but it doesn't make it any less stupid.

Riot, stop treating AoE with travel time as projectiles, if it isn't a projectile in the sense that it is thrown or shot, it should not be affected by Wind Wall. Ranged Auto Attacks and Skill Shots, I can understand, but a ranged AoE that has travel time should be allowed through the Wind Man's wall.
