Azir and counterplay
I'm going to preface this with the statement that azir is stupidly overpowered right now, and let you gnash your teeth about that while reading.
Azirs abilites offer little to no counterplay, from his q, which moves too fast to dodge without a flash type ability, to his soldiers that use attack/hit mechanics in an aoe allowing him to free farm while harrassing you (even under your own tower!)
Azir is a heavily skill based champion though, making it very easy to suck donkey balls with him, and his low win ratio is misleading because of this. And while to some extent I can agree that very difficult to use champions should have an edge over simple to use champions, the degree of strength should not be double the pre-nerfed kayle damage was. Seriously crack must have been smoked to come up with a 60% ability power ratio auto attack to an area on a champion that gains naturally high attack speed.
Even lowering the damage isn't necessarily the solution, as you can still be targeted under your tower, where normally melee champions, that are incredibly overshadowed by his skillset, would be able to huddle up and farm. His soldiers should be targetable, or move slower, or simply follow him and augment his own attacks, not be autoattacking at a distance of 1250 under the enemy tower.
