I am a Priest, sort of.
I am reading through Wowhead's review of the changes and found that Blood Pact now applies a stam buff. So what are Priests going to do in groups with Warlocks? I doubt it stacks to get 20% stam increase! I am also looking forward to my tundra mammoth for raiding and dungeons on my other toons. Hmm, running around questing with 2 friends and my mammoth! Great way to get from 10 on.. If you haven't yet, check out WowCrendor's run through of Scholo and Scarlet Monastery. The simplifications to the 'maze' of scholo and the complexity of 4 different entrances in SM are gone. Definitely going to make running Headless a bit different now that the graveyard is populated with flame-thrower wielding npcs.
