Found out about this like way back in PRE-BC but I just remembered it, and went back to try it, and sure enough it still works.
Enter SFK and right after you get to the Worgen boss with 2 bat pets, there is a pillar that is broken apart.

The video explains the rest.
The beginning is kinda boring, but the ending is neat.
Thanks for watching.
