Funny little exploit that I've just encountered, I didn't seen anything about it on ownedcore, so here it goes:
If you create a premade party using looking for group, even if you're the only member you get an option to roll need, greed and disenchant on all gear - even if you're on a toon without enchanting. I've recreated that twice just to make sure, but any confirmations are like always welcome.
Enjoy
EDIT: You do NOT need to have an enchanting building in your garrison for this to work!
EDIT2: While it works in open world in Draenor, it does NOT work in cata dungeons.
