Blizzard has revealed few details concerning the Blood Elves classes of World of Warcraft: Burning Crusade expansion. It is not a final roster of classes and things may change during development.
Eyonix: “I believe the current plan is to allow the Mage, Priest, Rogue, Warlock and Warrior as available character classes for the Blood Elves upon the release of the Burning Crusade. Much can change between now and then, however.
I’m reporting information based upon the latest design direction for the race, in an email dated April 24th. I don’t remember what classes Tigole specifically mentioned, but I do remember, just as I’ve done now, he stated that the information given was subject to change.”
