That's where you are wrong, Speicifc locatrion on all contents in the game: Northend, Eastern Kingdom, etc. Have a default location whereas the player, depending on race and or faction, is ported to a specific location and or the default location.
It's passive exploitation and nothing more, the player does not have to choose to go there. It's bugs your corpse/hearthstone and forces you out of the map because the server gets confused. Retail WoW suffers from this too, just Blizzard GMs are too naive and unaware of such a thing happening.
Solution:
*Mages who know of this can go there and get you out.
*People on the outside can make use of the Meeting Stone to get you out (server trick to summon anyone as well)
*Warlocks is another plus for summon
*A got whos capable of "skill" can get you out as well.
*Make use of Unstuck either in game and or website (one of them will port you to hearthstone location)
*Make ticket and ask a GM
Afterwards:
Go to an inn keeper and change your home location!
What not to do:
There is certain spots in the game map that will result in lose of control of your character, unable to log out and or move so you have to alt+f4, this is the case with Factionless Pandarens who fall through the floor in starter zone, same can be said for others.
