If the mage takes you to Blasted Lands you should be able to fix it by talking to Zidormi at 48.2, 7.2 within the zone. That should take you to the old version of the zone and should also fix the Thrallmar Mage teleport in Orgrimmar. Hope this helps! :D
That took me to the dark portal in Blasted Lands not where your video shows did they change it since you made this video?
