Even months after release, Azir is still bugged as hell.
Sometimes I knockback someone onto a wall and they will literally keep jumping and bumping into my soldier for 6 seconds straight without being able to move or do anything.
Sometimes enemies hit will completely bypass the wall, dealing no damage whatsoever.
Hell, Last game I had the ultimate not going on cooldown after I usage.
Somehow I was able to create not one but two Emperor's Divide during a fight, one right after the other.
I don't even know how I did it or how to replicate it. I know it happened.
Oh, sometimes my soldiers also decide not to deal damage to certain champions, despite their attacking animation dealing damage to minions.
I know how to trigger this bug tho, just use your Q and immediately Right click someone.
