Bug description: While watching other people play mage on Retail, I've noticed that they can teleport back to their previous location (where they casted it the first time) by using Teleport: Hall of the Guardian again. As shown in this video that I found.
Also WoWhead's Changelog also addreses the ability to port back.
Proof: https://youtu.be/J1FVffiMf7A?t=32s teleport to Class Hall , https://youtu.be/J1FVffiMf7A?t=1m59s teleport back to previous location. WoWhead's Teleport: Hall of the Guardian changelog: https://imgur.com/a/J1WP3c5

Uuuu, sounds very handy, dont think it will be hard to fix but we need a bit more info. What happens when you use it inside a dungeon/raid? If you use it again while in the guardian hall it ports you back to the entrance of the dungeon/raid or outside of it?

https://youtu.be/0-d_JyKc7uw?t=1m28s youtuber addreses that it will teleport you to the nearest graveyard or the begining if you are doing a dungeon or raid. After watching this again I heard that the teleport to previous location should work for Druids, Monks and Death knights aswell.
Edit: got a confirmation from guildies that it works for Druids, Monks and Death knights, but it doesn't work for mages

Have tested this, Does not teleport you back to previous location like it should. @kuro

Confirmed, should teleport you back to where you were before using [Teleport:Hall of the Guardian] kinda like a Death Gate or a Zen Pilgremage.
