Wind wall/Unbreakable and Azir interactions.

Yasuo's Wind wall is as stated: ACTIVE: Yasuo creates a gust of wind that travels forward to form a wall 400 units away from himself. The wall slowly drifts forward over 3.75 seconds, blocking all enemy projectiles with the exception of tower hits.

Azir's Q is a charging soldier not a projectile. Why do they stop at the wind wall? Same with Azir's Ultimate. Its a wall of charging soldiers, if they are strong enough to push a giant cho'gath away. I think they should be strong enough to go through a wall of wind.

Idk. Just me probably. (all of these work the same with braum's unbreakable.)
