New races would be a total waste of the limited time and money that is spent on upgrades to this game. For anything to be added something else must not be done. New race equals no money or time for new classes, lands, levels or fixes. Besides having a new race adds nothing to the game, the same skills and weapons with a different animation does nothing, eye candy and nothing else.
A totally new class with new skills would actually add something to the game it would change game play, parties, siege, etc.. That would be a worth while and people would spend lots of real world class to quickly level the new class.
