Remove the Range Limit on Azir's Minion Control.
As it stands his max range to use his minions is about Tristana range.
So if you're running, W-Q at the enemy you can't autoattack. This makes him feel incredibly clunky.
There is no reason to limit his range. They'll rarely be at max range of a Q, and only last 9 seconds. To auto with the minions forces him to stand still, too. He also has to burn his escape / engage to be able to harass in this way.
Limiting his attack range on a champion meant to rely 100% on his minions is... Clunky. Incredibly clunky.
