I wouldn´t bother with it now as far as trying to sell one. Next expansion those orcs and peons in N. Barrons are going to fall over if you walk near them and they are tightly packed together. Will be one of the easier things to farm on a lvl 95 (or 100).
I still haven´t heard anything about the LFR-Primordius ooze. Now if you are looking for something to buy 5 of and put in your bank for a year.. that would be my choice. That thing is going to be super rare next expansion unless they change it´s drop.
