Azir needs some major overhaul/nerfs
Late game hyper carry with a good laning phase is just not something thath can exist.
He even has mobility AND waveclear, like if this champion is up why would you pick anything else mid lane?
He needs to one of those :
- Lose his mobiliy/survivability
- Lose his burst (Q doesnt do damage anymore, just reposition)
- Lose a good amount of base stats (maybe make it so he has low base hp and very low armor scaling), so he actually becomes actually weak early game for his scaling/able to be punished by stronger laners.
- Lose his waveclear (make his soldiers AA single target)
Until something like that happens, he'll still be a fundamentally broken champion with no way to be balanced.
