I don't know why, but in the Wasteland area it reminded me of the Warcraft 3 area where you met Rexar, as he was a character you found around the new home of the orcs, but I can imagine the pressure healers and tanks must be under to be able to keep a teammate from dying
This zone is the neighboring zone to Durotar where the Orcs have their main city of Orgrimmar. Could be it's the same area as in Warcraft 3.
