Crazy Azir Rework idea! Slight wall of text.

Passive would be similar to live except it doesn't replace a dead turret. Azir instead Shurimafies a friendly turret by covering it completely in sand. The turret health bar is replaced with the sand health bar that decays over a minute and increases turret damage based on AP. Has a 2 second cast time of the sand slowly covering it. If Azir or the turret die during the cast time then the cooldown is reduced by 50%.

Q would be the same except deal no damage, have a heavily reduced mana cost and cooldown, and no longer slow.

W gets a few changes. Soldiers now have a health bar and can be targeted but they last longer now(by 2-3 seconds). Azir will have a slight mana cost reduction, faster recharge, and at level 12 soldiers passively take 25% reduced aoe damage. Soldiers can be cc'd but will move no matter what right away when Azir uses Q. Soldiers die to 1-2 turret shots no matter their health(will scale off AP) and they can auto turrets but turrets can only take damage as if only 1 soldier was attacking it. Turrets prioritize soldiers unless Azir is in tower range attacking the enemy.

E costs 1 soldier charge and gives Azir a shield based on his AP. Azir will gain 50% increased soldier respawn time for 1 second after casting E. Shield comes out and after 1.5 seconds rapidly decays away.

R would be the same but no longer damage enemies. Instead of damaging them Azir gets more soldiers summoned and they last longer. Soldiers from this spell can be attacked but they take 90% reduced damage if you attack the shield side. They cannot be cc'd or repositioned.
