Along with Blizzards new option to be able to Disenchant roll for loot instead of having a DEer collect the stuff and then hand out mats at the end of the instance comes with a new flaw allowing easier farming.
Like me, a lot of you Mmowned users have probably tried farming Converted heroes or other Northrend mobs to make gold fairly quickly.
The thing that always dissapoints me is that the greens/blues you find, unless you are an enchanter or take the time to find an enchanter in trade chat and what not, always get vendored for a fraction of what the enchanting mats could have sold for on the AH.
There's a few steps in order to perform this exploit, but it will allow you to be able to DE things while you farm on your chosen mob.
1) Find an enchanter in your guild or a friend that won't mind being in a group with you.
2) Make sure you're the party leader, and queue up for a heroic, make sure you have the party leader checked in the queue window too.
3) Simply use the mini map teleport out of dungeon icon to leave
4) Travel to the desired farming location and do as you normally would.
Using this method, we can abuse the Disenchant roll option when a green/blue drops, provided the enchanter stays in your group. As long as you're the party leader and your enchanter friend doesn't help to vote kick you. You won't be kicked from the party.
I don't have pics, but it's pretty easy to pull off and works like a charm.
