This is totally not true.
I mean, I didn’t get EVERY combination. I became a mage a whole lot, and a hunter disturbingly often (Does it know that I used to raid as a hunter in TBC or something?), and the occational druid. I’m pretty sure I didn’t get a warlock.
Everyone else and their grandma – well, those on twitter at least – seemed to become nothing BUT priests. I’m pretty sure this is some sort of conspiracy.
