As I stated before, one of the worst times to try and make gold is at the end of an expansion. However, one of the best times to make gold is at the beginning of the expansion. People will be rushing to level up their professions, so folks with gathering professions will be out in full force looking to take advantage of the lazy crafters who will buy up anything on the AH that will level up their profession of choice.
I am actually prepared for this. During one of my frequent bouts of insanity, I leveled a Blood Death Knight up to 60, gave him the Mining and Herbalism professions, then boosted him to 90 which maxed out both professions at 600. Once Warlords of Draenor goes live, my Blood DK will head out into the world looking for stones to dig and flowers to pick, and since he’s a Blood DK he’ll be unkillable. That’s money right there, money I’m hoping to line my pockets with.
As luck would have it, WTBGold has started doing some research into the various professions in WoD. He’s hit the alpha and started poking around, noting various changes and so on. He’s just getting his feet wet, but if this Herbalism Guide is any indication then this will be the channel to watch going forward.
