WoW World Of Warcraft Gold Earning
5 Gold per Hour - Requires Fishing at 100
If you go to the fishing hole outside of the Wailing Caverns, you can fish for deviate fish. These sell at 5 gold per stack at the AH. With fishing at at least 100, you can fish 20 in about 45, so with travel time, its a sweet 5 gold per hour.
An even sweeter deal with the deviate fish is the savory deviate delight, made with deviate fish, these sell outrageously well in the Uldum AH.
