This is just my speculation to the idea of Ao Shin. A million to one though this isn't what its gonna be. XD. Also, I respect LOL Wiki people ideas so I'm calling him the Storm Dragon, though he can't control storms in Chinese mythology.
Also, Ao Shin has great support rates, but it is to be understood that building him support is completely different because support build will have its rates based on health, while mage form will be based on AP
Just a few notes: Ao Shin is best used by fulfilling both lanes. getting items such as rylai's crystal scepter, Liandry's torment, and rod of ages can help with that.
