rolling Draenae

[Xanthix]

Which class?
...
This leaves the hunter, priest or mage. I have not played these classes, which makes all of them attractive.

The Draenei +hit% aura and HoT would be very attractive to a hunter I imagine.

But overall I would worry about racials less than playstyle. Any class can gather minerals, but you'll have to level up to 35 to get 315 jewelcrafting (maybe higher if the cap is raised from 300), so pick a class that sounds fun for you.

I'd also probably wait until more about level 70 skills are previewed. Some class might get a 41-point talent that you really want to try.
