Using this method you can now get to the new Tomb'ish area, (it is supposed to be a 10 man lvl 70 dungeon in the expansion) below the Towers in Deadwind pass.
It is rather simple to do. If you go to the Tower you can see a instance entrance behind a closed gate. You cant use fear/poly/ghost to get in there, but further down theres a crypt entrance with a gate as well. If you pull one of the hostile ghost here and let it kill you, the graveyard is close and you can rez on the opposite side of the gate to explore some of this new content.
