Azir is absurdly overpowered, single handedly ruining this game

Too many strenghts too little weaknesses. His range his damage, his engage, his disengage, his mobility, his seige, his poke when is it not the best time to pick this champion? He is picked every game in the LCS, and in solo q and for the right reasons. I believe a balanced champion should have a balance of weaknesses and strengths. That is out of the question for Azir. Teams are limited to the use of poke to be able to take down a champ like Azir in the hands of a good player
