I knew right away that i was going Tribal leatherworking (on the horde side) so i can at least help with getting THAT.
From what i've seen, Tribal has a lot of int and spi boosts (Ironfeather set), and well as Str and Stamina (with the Warbear set), Stamina and attack power (with the devilsaur set), and the Chimeric and Frostsaber giving you all the resistances.
From what i've heard and seen from Dragonscale and Elemental, they dont have this much variation, with the resistances and int, spi, stm, and str boosts.
Unfortunately theres no agility in there for you rogues...
To get tribal leatherworking, its a pain. You have to go and talk to the guy in Feralas at Camp Mojache (don't remember his name, he's in the big tent across from the Inn). He gives you all the wild leather quests, which you have to complete (theres 5 of them in total) in order to be able to get a straight answer out of the Tribal leatherworking (who is directly south of Grom Gol, across the river from the big fat blue bad guys). You need TONS of turtle scale...i cannot stress this enough. I am so sick of killing turtles. and you need Wildvine.
Once you've done all 5 Wildleather quests, you talk to the Tribal Leatherworker who gives you a quest to make a Wildleather Vest and a Wildleather Helm. just one of each, that takes 22thick leather and 4 wildvine...and some thread, i think.... and 2 cured thick hides...
anyway, once you've given him these two items, you get to be a Tribal Leatherworker, he trains you in Ironfeather Breastplate and Wolfshead Helm, and the rest of the patterns you gotta pray for drops or buy off the AH.
hope that was in any way useful.
