What if Azir E cost a sand soldier charge to grant him a nice shield?
Instead of being some hyper mobile champion with his E he gains survivability instead(that is reliable).
Maybe make the shield based on a decent chunk of his AP but dear god no health scaling. Ap champs have health in almost every item now and it is really annoying.
Also when he uses E his W recharge time is speed up by 50%. So if he recharges in 10 seconds he will recharge in 7.5 instead.
