@Riot Azir ult can result in a 5-7 stun/snare
I experienced this in a match last night, I do not believe it to be a bug, however I do believe it is unintended. If an Azir player uses his ult against a wall in the right way you are rendered unable to move or react for the duration. What appears to be happening is that you are trapped inside of a soldier's hit box, and if try to move the soldier slaps you and knocks you back. (If you look there is an animation associated with this for each soldier) Unfortunately if the wall is thick enough it can't knock you through it and perceives you to still be inside the hit box, resulting in you being juggled for the duration the wall is active. This effectively results in a 5-7 second snare/stun. While I do love Azir, this is incredibly oppressive and believe it should be examined.
