Dying in some locations within the Caverns of Time will send you to the graveyard in Tanaris. This is a much longer run back and surely is ridiculous that the game will send you to this graveyard when the CoT graveyard is 10 mins less of running in ghost form to get back to your corpse.
With the upcoming release of Hyjal, this should be fixed to send you the the CoT graveyard whenever dying within any location in the Caverns of Time. I understand that the Tanaris GY might be closer “as the crow flies” when looking at the zone map, but in reality it is a complete waste of time to send players there when they die in the CoT zone.
