I really hate Azir
Actually this isn't a complaint about his current power level. The problem I have is I have no idea if anything people say about him is true or not. He's too obscure. Not that many people are competent with him. Every time he gets changed there are people saying things like either he's too strong or he's unplayable trash. It's impossible to tell if anything is true or not.
So I go look at his changelog and I have no idea what I'm looking at. I don't have the faintest idea what the changes actually did to him.
How does Riot maintain a champion like that? Well I guess they don't if his patch history, winrate and playrate history say anything.
