That's not even it though... do you "race people" ever think that the team has to create a whole seperate starting area for them, new skills, attributes, gear, quests, and all that just for them.
As of right now I don't anything with new races will be implemented anytime soon due to the team we have now. I'm not sure if they can even do all that from scratch anyway, maybe they can but that would take a hell of a long time.
Just let the team do what they are doing, because dbo was good the way it was, no need for new races. Also you should try all the races ingame before trying to suggest new ones.
