Yes yes, useless, no dupe, no real exploit etc but its fun and wow @ the upside down sinners.
Like with the Hyjal thing you can get to the new tomb'ish area (supposed to be a 10 man lvl 70 dungeon in the expansion) below the towers in Deadwind pass.
Anyway, its pretty simple, if you go to the tower you can see a instance entrance behind a closed gate. You cant use fear/poly/ghost haxX 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 conent.
It looks pretty neat, cba to post pics where exactly it is, you lazy twats can find out yourself, takes you 5 mins
