It has come to my attention that it's possible to open the DME door ( after jumpdown), without having to talk with the tree, or kill the first two bosses.
This exploit originates from a bug in WoW, not from nostalgius, however it can be used to farm DME quite fast (talking 5 mins runs with 2blue drops + mining), for a lot of money.
Now I heard that doing exploits like going to Hyjal isn't bannable, but is opening the door to farm DME quickly a bannable offense?
