Sorry if this has been posted before, anyways if you are pvping near a instance and you want to get ouf of line of sight to heal or whatever and not actually go into the instance, right click your portrait and go to dungeon settings and click heroic and if its a low level instance you can't enter it and you will actually go behind it(I was doing it at SM when Horde and Alliance pvped while waiting for HH groups, I am a healer btw). I use it to get out of line of sight and come back out and throw a heal, it's kinda useless if you are a melee class though... Sorry first post, please flame away at my nubness in commas.
