Revert the Azir W Range Nerf
The Azir nerfs were very heavy handed. I believe Azir was designed as an sustained damage mage with good self peel. The nerfs to his W range just feels terrible overall if you played Azir before this nerf. His only reliable damage with the terrible range on W is to W into Q(which was nerfed as well) and a single auto, maybe two if your lane opponent is braindead. This leads to building, in my opinion, straight AP to get Q-1 auto W burst, which is not what he was designed for.
I propose increasing W's range to pre-nerf values, and if his lane bullying is still an issue, increase the CD of Q and have it decrease per level. Therefore, in lane he has to more carefully use Q to reposition his soldiers.
