Project: Yasuo's Wind Wall doesn't Block Projectiles all the Time.

I just wanted to let you know that I enjoy this game and the skins that you guys provide for your champions. The one in particular that I wanted to talk about is Project: Yasuo. This skin is great by the way. I have it set as my main skin all the time. Something that I have noticed from time to time though is that it does not seem to block lock on projectiles as well as the classic skins wind wall. Sometime I will clearly use it way before Katarina throws a Q and it sometime will block it and sometimes won't. What makes this irritating is that I now have that doubt that my wind wall will not block projectiles all the time. Usually when this happens it swings the game in that persons favor all because the wind wall did not do what it was suppose to do. As I said I clearly used the wind wall before the projectile would hit me and it would just go through the wind wall. My reactions would be like Huh? So could you guys please look into this. I don't know if their have been any other reports of this but it has happened to me several times (not every game but it happens on occasion). It has always been lock on spells like Katarina's dagger toss or LeBlancs Q's that have caused the problem. It always blocks big ultimates like Cait, Draven, and ashes ults. So the problem seems to be just with lock on projectile abilities. Please look into this and feel free to reply back to me as well. Thank you.
