Also the idea of zoning into one area and being in an area doesn't quite work - meaning zoning into DeeprunTram and being in BWL. There are ways to do such a thing, but instance swapping alone won't get you there. When you instance swap, you are still in the origional instance, just with the textures/terrain of the swapped instance. Meaning you are still in the DRT, but to you it looks like, say the black morass. When you do /who on your self it will still say you are in the DRT. Therefor you won't see the mobs or the rest of your guildies.
