[Gameplay] Yasuo Wind Wall

I'm recently picking yasuo back up and I don't know if riot changed the way wind wall mechanics worked during recent nerf changes. But in recent games there would be frequent occasions once i cast my wind wall the current spell against me would go straight through it. An example from last game i was against a tf as yasuo once i would see that tf had his stun card up for me i would letting him think i was playing into his hands by dashing up to him. Once i was in his auto range for him to throw his stun card at me i tossed up my wind wall and his stun card went straight through it. I thought once the wind wall was summoned it would block all incoming ranged projectiles. I've noticed this before you reworked trist I thought to myself someone probably already posted about this or riot already knows about this bug. But in the era of the mid lane tristana i would throw up my wind wall (Knowing how slow the buster shot moves) and the buster shot would go straight through my wind wall. As a yasuo player when it comes down to those clutch plays that include your wind wall the result can be quite annoying >.< (that mechanic/bug ended up costing me my lane to tf allowing him to snow ball) i could be 500 hp and he be 200 would pop wind wall and still get hit by his stun card spelling out my death. Lastly, what i noticed is that this bug doesn't really occur against larger spells like jinx ult or ezreal ult i could pop wind wall a second before it's able to hit me and it would be perfectly fine.
