League of Legends (LoL) Question: Azir mid after nerfs atm

He's still a great pick and a strong zone mage. He has recently been picked up in the competetive scene quite a lot if that matters to you.
He hasn't been touched by Riot in the last four patches but there've been changes to some of the common mid lane matchups. In patch 5.5 he actually received a slight buff as they increased all kinds of ranges on his abilities.

Azir is still a very strong champion, but I think there are better picks since no matter how much farm you get, you'll never be as strong as you want to be compared to your opponents unless you snowball which is very difficult to do on him... I think a hyper carry and just a standard burst mage is better than two late game carries. He's very strong and super fun to play but it's only under certain circumstances.
