Aatrox's walk animation (with his sword not drawn), has been not properly synced for at least a month now. The animation cycle clearly misses frames (at least on his gauntlet arm). You can especially see how his gauntlet hand pretty much teleports/snaps every 4 s, while walking.
Edit: his right banner is snapping too
Not to mention him still missing a joke line. (But that has nothing to do with a bug, as far as I would guess)
Could you please do something about it. Multiple people already have brought it to attention in the past. Not sure if on any forums, though.
