Usually Hunters in World of Warcraft have to make a decision between increasing their rank in their chosen professions and buying food for their pet. One way of avoiding this particular problem is to take two gathering professions. By doing this, everything you gather you sell and you won’t be worried about using up any of it because you won’t be able to, instead you can use the money to buy those items or consumables.
Taking two gathering wow hunter professions will allow you to simply gather up what you find along the way during your adventures and then selling them at the AH once you have a full stack of them. A lot of professionals who change professions at either 70 not so long ago, and from now on at 80 will prefer to farm the AH for cheap material rather than actually doing the gathering on their own.
Skinning is a great profession to take, because you’ll be killing a lot of creatures and the leather that you get from their hides will prove to be rather valuable in the long run. Sure at first it won’t fetch you incredible prices but as you level up and your prey levels up as well, you’ll see the amount of gold that you can charge for stacks of leather increase.
In the same vein Mining is a great gathering profession choice and one of my favorite because there is a need for ore and or bars at any given time in the game because there are three main professions that need metal: Blacksmithing, Engineering and Jewelcrafting.
