[GAMEPLAY] Aatrox stuck in the air during passive

So the basic gist of this event is that Aatrox is stuck mid-air if he dies during his q and is sent into his passive.

This means that when you come out of your passive, it takes a second to fall. Also, in one instance, I had an elise and pantheon stand under me, so that when I came out of my passive, Aatrox was pushed away from the champions as if they were taking up the space under me.

This is confusing because I was brought to believe that League of Legends has no y axis. Why was I pushed away from pantheon ? I was an auto attack away from killing him too, but I couldnt because I was pushed away from him.

I'm not sure what caused me being moved, but in general it is an extremely disorienting bug. Aatrox's Q has very odd physics and it makes him awkward to play, which is disappointing since he is my favorite champion. Other things I have encountered during Aatrox's Q include:

(not sure these are all bugs, but they are strange anyway)

• being auto attacked mid air
• q going off cooldown if I cast it during a stun (not before, during)
• q being canceled before the animation goes off
• being returned to the point i casted q when hit by a stun instead of falling straight down
