Who should i buy Kayn or Azir?

azir is a lot of fun, pulling off plays with azir is way cooler than kayne, anyone could pick up kayn and do okay with him. Azir is just hard and cooler

I'd wait a week so you can see what you can get in the BE shop. You can get Kayn/Azir later.

Personally, I despise Azir, so I'd say go with Kayn.

I guess it depends on if you want a jungler or mid laner, but I'd pick Kayn. Way more fun and interactive. Azir = toss out a couple sand soliders and auto over and over. Zzzzz.
