Improvements/balances to Azir

After playing Azir every game since he was released I have noticed a few areas where his kit/gameplay could use some polishing.

1: (kind of a bug) his abilities are a bit unresponsive/ delayed, particularly his ult. Having to repeatedly click to use an ability is very unrewarding and frustrating. His play style is already very different and requires precise timing so to have it delayed by an unresponsive kit is.... maddening. Regarding his ult it inconsistently blocks or pushes back enemies especially if they are trapped between it and terrain, often they are bumped over the ult wall by a collision with terrain.

2: his passive "Disc of the sun" seems a but under powered. I have been playing him PvP (not this account) and the laning opponents are able to dive under a Disc turret and shrug off the dmg... I understood it was supposed to be more powerful than the standard turrets but it appears that is not the case.

3: I understand that you wanted Azir to control his soldiers as an emperor from a distance but I find my self being out ranged by most lane opponents and pushed beyond the control range of my sand soldiers. I suggest his control range be increased slightly to improve his laning phase as he has very little sustain. He is often bullied away from his soldiers due to their low dmg output as well as the close range required to command them.

Ultimately I feel Azir is quite well built and decently balanced but could use some polishing to really allow him to come into his own. Let me know what y'all think.
