Nerf The Azir Riot!
Don't even need to say why he should be nerfed cause it should be clear as to why.
I do want to give a suggestion to how they could nerf him while keeping his identity and kit intact.
So on his Q, and his E, the range the sand troops that travel needs to be lowered by a whole lot. Lower the distance so he needs to be closer to you, To compensate, give him back his knock up on the E, but otherwise, make the distance a lot shorter.
That's about it.
I'd probably nerf him more honestly like his soldiers attack speed can only reach a certain limit. He shouldn't be able to attack that fast while being safe, and there should be a limit.
No one will probably agree that Azir needs to be looked at and toned down once and for all cause his name don't start with an E and he doesn't go to the top lane, but I rather face anyone than an Azir in lane, and rather have anyone on the other team than an Azir.
