Vel'koz's W and Yasuo's Windwall
So, my question is this, why does Yasuo's windwall, stop Vel'koz's Void Rift? I mean, it's not a missle for one, and for two, it's opening a rift in the ground, which should actually be UNDERNEATH the windwall of Yasuo. So, why is it blocked? Then it shoots UP, not forward in an explosion. So can someone, preferably from @Riot, explain why this happens? It just doesn't make sense to me as to why it is blocked when it's not really a projectile/missile, and it is from underneath the windwall, so it should just bypass it. Can this be changed?
