Hello Ownedcore! This is one of my first contributions, and it's a pretty major one at that. I don't think it's a repost, as I searched and found nothing.
Highborne Soul Mirror - Item - World of Warcraft is required for this exploit.
First off, you have to do This exploit (Stay In Any* Temporary Transformation Permanently) with the Metamorphosis gained from the orcs in Durotar at Razor Hill.
After you have your permanent meta form, go to somewhere crowded (VoS AH, Bank, whatever floats your boat) and use the highborne soul mirror. Watch people spam trade about their wow crashing after a few uses, perhaps just one or two if you're on a crowded server
