I decided to roll a DK as an alt to toy around with for a while and finally got out of the beginning area and well, I'm not having much fun.
I'm only level 60, and haven't gotten the grasp of it but it just feels slow, especially waiting for runs to turn over.
Depends on spec. Blood is super strong right out of the gate with BB just decimating everything. But mostly it'll be really slow until you get the T75 talents.
