Rom Gold players are still going to be a playable race.
With all this talk of phasing it would not be hard for them to phase out Orgrimmar between Garish leadership and that of someone else (heck raids could be against the same boss who appears differently to different people). It would make sense, really. I do not really see Sylvanias as the type to bend knee that will make you more Rom online Gold. Well,Rom Gold players are still going to be a playable race so we must expect some kind of respect (and not outright Forsaken internment camps like the one in Altered) given to them and their starting zone. Yet, at the same time, we have to assume that they and the Blood Elves are not going to be getting any preferential treatment. They also probably will not be seeing undead only cities again without Rocs breathing down their back.
