Azir's requires to much work for so little pay off

I have been trying ti play Azir for a minute now and my success with him has been just so so. Even when I did win a few games with him I did not feel as if I carried or was a major benefactor in team fights . I find myself having to do so much to drive people back and out of lane. With him having no real burst damage that is just it--people simply walk out of lane. The AA range on his minions feels to short in addition to the repositioning of them as well. His CC/Escape feels limited/situation and over all lack luster. Your damned if your opponent has a speed boost of frequent gap closer. I am willing to also toss things up to me simply being mediocre with him however, I cannot think of anyone actually carrying with him as well. I know I may sound like the minority but I honestly think he needs a buff or two--hes simply to exhausting....And why does the proc from the Frozen Gauntlets work with his soldiers. I mean after all it is an on-hit effect right ?
