For me, personally, my moneymaker is Normal Vortex Pinnacle. Yes, its a Cataclysm dungeon, but its Money, Jerry! Volatile Airs still sell for about 25 gold each on my server, and killing everything up to and including the 2nd boss, I can net 20 or more Airs in a run. Not to mention the money drop and greens. You dont get cloth until you go past the 2nd boss, which I dont do, I just leave, reset, repeat.
