So this is a very newbish question which I guess would make since because I am new to this game, although very familiar with mmorpg's in general. how do I go about getting mats for leatherworking? By that I mean... well take carpenter for instance: to gather wood one would take botany. With leatherworking I am dependant on skins and hides but it seems the way to acquire them out in the world is by killing mobs and acquiring their drops, but the drop rates are far too insufficient to make do for advancing my craft. Am I to rely on the auction house? It would seem odd seeing as how I already have to rely on that for some of the other materials I will need. If that's the case, no biggie. Just want to make sure I am doing it right.

P.S. I am aware my the leather working guild sells mats but that seems only viable for a few tiers.
