These forms and locations are listed in my classic gold of wrath WoTLK Gold guide, that is once three times listed below in the way. Next is rogue pickingpocket farming. It's more an orange type of farm. It could give you 200 gold per hour, or offer you 1500 gold per hour. It all depends on the luck of the draw. But this is actually an enjoyable way to mine gold. And it can be incredibly profitable.
Also, it doesn't require any specialization whatsoever. Also, since you're not killing any thing, it doesn't need any equipment either. However, it is locked to a single class, which is rogues. That makes this kind of model a special. There's a form that was discovered to be truly amazing, and it's located in Sholazar Basin all the way to the north on the mountain where you are able to steal the zombies.
This being said, I'm expecting this to be the rift that will be way over farmed. But there are numerous places in Northland that you can earn plenty of gold by pickingpocketing. If you are pickingpocketing, you can get potions, Venerable items and raw gold and in raw gold, you're producing decent quantities of gold up to 200 gold per hour, subject to your area of residence.
That being said most of your gold actually comes from opening the lock boxes, where you have a chance to obtain rare gems. They will be selling for a lot of gold in the very early phases of the rough phase, however, the profits from this will fall off drastically in time. This video is about the process of forming gold in the initial phase of cheap WoTLK Classic Gold anger. So rogue pickpocket farming for lockboxes is definitely something worth talking about here.
