When Cata dropped for WoW I leveled my druid first (he was Herbalism and Mining) I made over 100k gold in the first 2 weeks from farming matts and selling them while I was leveling to 85.. The prices were jacked up over 500% at times because everyone was trying to get their proffessions maxxed..
Will anyone else be capitalizing on this? It will be a new game so its just speculation right now but after looking at how the market shapes up at release I think it will be much more beneficial to sell all your crafting materials and let everyone else get their artisans maxxed out early on..
People will be craftng MANY of the same items looking for perfect stats and selling the ones that are sub-par and crafting more.. meaning crafted gear (imperfect affixed) should be reletively cheap compared to the crafting materials.. so you could just sell the materials and buy the gear you want and most likely make a bit of dough in the process..
you can always go back and maxx your proffs later when the market stabilizes and you already have good gear and a lil money in your pockets..
