To all of the Azir mains out there!

I just wanted to say that I used to think azir was just another easyish champ.. you know as in a champ with low skill floor etc. But I played him I believe for possibly the first time the other day? His skill floor is probably one of the highest along with his skill ceiling! It's all opinion however as different people grasp understandings of different champions at their own pace. Anyways I wanted to say I have a new found respect for all of you Azir mains out there! :) I just hit 6,400 IP, So I decided to make him my next champion(I absolutely love his joke i think it is? the one where he walks like a bird? XD) Okay back on topic.. If you're an Azir main and not an absolute total jerk, I have respect for you by default =] That being said, if anyone has any tips for someone looking into playing azir feel free to let this summoner know! :) By the way.. are his builds pretty flexible? from my understanding nashor's is a first rush item, will his soldiers proc rageblade? Does he have any interesting builds that anyone can think of? Thanks for your time! Also thank you for your feed back if you decide to answer any or all of my questions and I'll see you on the rift! ^_^
