Whether or not you RP, do you create a backstory/lore for the characters you play? Do you name them and transmog them according to the story you've created for them? What is your story for your character? How important are they in the events in WoW for you? For me, I don't RP at all since I'm on a PvE realm, but I still like to create stories for them.
I recently made a Pandaren Shadow Priest, which I rationalized by saying they are afflicted by the Sha. I gave my Pandaren shaman the title "of the Four Winds", saying to myself that not only is he a Shaman, but his ancestors came from the valley of four winds. My mage, Arcanagosa, is a blue dragon that takes the form of a Highborne sorceress to keep an eye on the mortals.
