which one has a larger profit margin?
None, they are all a money sink, if you work it extra hard you may get some gold out of any branch, but that takes work.
To make money out of any crafting profession, the player has to be the kind of person who sits arround on alla, reads all the mats for the diffrent branhces, then checks the AH on There server to see what would sell best on there server. Keeping in mind that if what you wanted was money you would not be in leatherworking(mining or herbology is a great companion to skinning for those who just need money).
Regardless of your choice to do elemental, tribal or dragonscale, the mats for all 3 outsell the crafted items, so by crafting ANY branch of leatherworking you dip in to a negetive profitt margin. Yet a open mind sees there is much more to a craft than the money, there is use.
Some slightly sellable stuff
Blue dragonscale gear, shaman can use this stuff, I would only loose about 5-6 gold if i crafted a set of the 3 peices rather than selling the mats.
Dragonscale gloves,Dependent on server age, you may be able to break even making theese vs selling the mats on the AH, everybody loves a lil cirt, both shaman and hunters....
The devilsaur set, while you cannot buy mats at the AH, Craft and sell for a profitt, you can make just about the same gold on crafting the items vs selling the skinns needed.
The Epics, each branch of LW can make a epic cloke, the one most purhcased is the "Hide of the Wild" that is made by tribal leather workers, if a person has all the mats, i usualy make 2-6 gold for making the item.
So the awnser to you question, and your snakry reply to the sticky that you did not fully read(the awnsers were there, but you had to click a link) is, none, there is no branch that will make you money.
