Perhaps this was somewhere in all the fine print of the expansion, but I stumbled across this interesting anomaly over the weekend: A blood elf can do the blood elf starting area, then move to UC and do the undead starting area, then the orc/troll starting area, then the tauren starting area, etc. No biggie. An undead character, once it finishes the undead starting area, cannot do the blood elf starting area. The quest givers are there, you can talk to them, you can read the quests, but they have no exclamation point, and the thing to click in the text box to get the quest is not present. Interesting.
