Isn't gonna give you up
Farming Whiptale herbs got me 5k in one day. I sold a darkmoon deck for 22k and made a mate one for free. Single darkmoon cards for for 1-3.5k each, but honestly not worth making. You could sell the ingredients for more than that. Also selling glyphs for around 100g each and some relics for 1k. But yeah, mostly just selling the herbs I farm. I did it when the rush was active, 1 stack of herbs would go for 200g+ and embersilk stacks for 200-250g. It's quite odd, beforehand I'd never have more than 5k.
I actually missed the whole early expansion rush...couldn't be bothered...Only character I used my was Hunter with his Mining/Eng
I stuck to reselling blues/epics, pets and rare recipes
I never bought anything from AH, abused guildies for their professions (everything from belt buckles, flasks to gems and various profession pets)...at one point I farmed 10 Pristine Hides worth of mats got a guildie to convert into armor kits and sold them off at 1k each
Sniped a couple items off neutral AH and made 300% profit on those...such a potential gold mine there
