Azir should gain a passive on his Q and his E.
On his Q, he should gain a passive to deal 1/2/3/4/5% bonus damage based of his current AD. It's not much.
On his E, to compensate for the passive nerf and loss of a knock-up, he should gain 2/4/6/8/10% cool down reduction for all his abilities.
I honestly wonder why Azir's kit mostly revolves around his W. It's either we do this or we make his W free. I know that Azir isn't in the best place but if his kit revolves around a spell that lasts 10 seconds at best to use his Q and E, he should gain passives or free use of his W to compensate. Not even a R that (lets be honest) gives free CS to enemy champs is enough compensation for this.
