Been bumping around on my DK. It's a LOAD of fun. The levels are fast, the quests are bloody epic. Lets not forget the free ride on a frost wyrm! I'll be rerolling DK in wrath. Fist, and final. I love it.

Things I've noticed:

You get talent points as you do quests/level.

You can change NE markings, and Draenei horns at the barbershop.

You turn green if you get the bloodworm talent in the blood tree. (/sigh)

Horde/alli start at the same place, doing the same things. (yay pvp!)

PvP on a DK is FUN. (lolol GET OVER HERE).

Once you've completed the last DK quest, you can no longer talk to the lich king, or see him. You can not go back down to the questing area.

And now, screenshots!
