What is the best way to farm for gold in WoW
I mean legal gold farming. The best way it to grind faction from level 57 when you enter Outland. Do the instances and get ur heroic keys and do as few quests as possible to keep them from going gray. Then once you hit 70, do all the quests in Outlands. You get the money from grinding out the quests and you get the big pay off when you turn in the quests which is 10-11G each.
This isn't the only way but if you are not in a huge raiding guild and want to solo as much as possible, this way will get you big sums of gold. Sure it will be slower by sacrificing the xp in the quests but how can you turn down 10g a pop?
