Ok after i loged on to about 20 different server i figured out that "Razorfen Servitor - NPC - World of Warcraft" outside of razorfen kraul drop alot of money lets say your on a server with like 20 gold rate a lvl 61 mob will drop like 1gold these will drop more but please comment back if this doesnt work on your server.
oh an P.S. the mobs show non elite but they hit and have hp like elites so beware.
