What i do to earn gold.
I. Buy low , sell High (I bought two days ago , 9 stacks of saronite , 3k gold, price/bar was about 16gold; I sold at the AH for 35g+/bar)
II. Prof's: I have Mining/JWC (actually never earned any gold with JWC). Mining = Ores & Crystallized Water/Earth/etc -> Eternals & Green / Blue gems. Sell that at the AH.
III. Farm Eternals (Wintergrasp is the perfect place for this)
IV. This is just an idea , if you have a lot of gold , Control AH. What do i mean by "Contrl AH" ? Let's say Titansteel Bars. There are 10 pieces at AH , buy them all , then sell them with a bigger price.
That's all.
