Azir as Tanky Support
This might be completely troll-status, but I have been screwing around with Azir as a bruiser/fighter support on bot late and it has been actually working out pretty well. Building sightstone, frozen heart, sorc boots, aegis->locket, liandry or rylai's, hourglass. Basically with all of his CC I was thinking that since I stuggle taking him mid that I'd try other roles. He still puts out okay damage, but the real prize here is that he becomes pretty durable, and with his CC and escapes he kind of forces the enemy team to waste a lot of time pinning him down. And best of all, you can be the initiator and push somebody out of position with a tanky build.
I'm fairly sure it isn't the best way to play Azir, but it's really fun, and I feel like I am helping the team a lot by setting up plays with his dash + flash and ult.
