Skinning is a great profession, because you will be killing a lot of creatures and the leather you get from their skins will prove to be quite valuable in the long run.
Many professionals who change professions in their 70s not so long ago, and from now on to the 80s, will prefer to cultivate HA for cheap material rather than doing it themselves. Taking two collecting wow hunter professions will allow you to simply collect whatever you find along the way during your adventures and then sell it in the AH once you have a full stack of them. By doing this, everything you collect you sell and you won’t worry about spending anything because you won’t be able to, instead you can use the money to buy those items or consumables. One way around this particular problem is to choose two gathering professions. Hunters in World of Warcraft generally have to make a choice between increasing their rank in their chosen professions and buying food for their pet.
