Yasuo Wind Wall bug

Often times Wind Wall won't block projectiles that come from point-and-click abilities. Considering Yasuo is pretty much a "do everything perfectly or screw up one little thing and die" kind of champion, this seriously skews his laning and teamfighting. LeBlanc was able to Q me so many times without my Wind Wall blocking it it's insane. In order to reproduce this, you need to get a champion with a point-and-click projectile ability, have him fire it at you, and when the projectile is near you, use Wind Wall. Because of how those abilities are coded I'm inclined to believe it sometimes just "clips" through wind wall because the projectile is further than it actually shows. It's infuriating and happens most often with Kayle's Q, Malphite's Q, LB's Q, GP's Q. Before you say that Wind Wall doesn't block anything until it reaches the location it always travels out to: It's not true. Any Yasuo will tell you that, you can even block a skill that's right in front of your face if you have good reactions. The skill has NO cast time, so it should work instantly. I wrote about it long time ago to riot, but this bug is still there, so I hope it gets fixed. EDIT: Just played against Nunu and I noticed something peculiar: I was able to block every single one of his E's, but the E went almost all the way through my wall if it wasn't put down in advance. But due to his E's low speed it got blocked. My theory is that point-and-click spells check much less often for collision with things such as Wind Wall, because they were coded long time ago, when the concept of Wind wall wasn't even there, so they happen to just go through sometimes.
