( For Horde mainly for alliance too if you can be dammed to travel) This holds 2 bugs
1. Hearthstone - Main City - Thunder Bluff | When you port there you will fall thats not suppose to happen if im correct that means that the spawning location is too low and will make you go trough the ground
2. Once you fall and die you will be at a spirit healer and you can either wait for the res accept option or you can use the spirit healer in both ways after that you will be alive but once your there you will see a NPC Teleporter were you can travel to various locations and malls and more which isn't suppose to be there for average players.( this might not be a bug but it still is a problem
