Of course, mail armor falls under the Dragonscale area (duh!) - primarily for Hunters.&nbsp Elemental has some good stuff but is primarily focused on rogue benefits.&nbsp Tribal also has some good stuff for rogues but primarily benefits the druids.&nbsp Of course, all leatherworkers can make the Scorpid (mail) armor - the majority of LW items remain open for all.&nbsp The really good items for all LW require Friendly, Honored or Revered with some faction (Timbermaw, Zandalar, Argent Dawn or Cenarion Circle).&nbsp So, the question is:&nbsp do you want to make items to sell or items for personal benefit?&nbsp I would guess that rogues provide the largest specialized market (Elemental) and hunters the second but farming for materials increases the difficulty of the DS area (none are easy materials to get).

So just off the top of my head here are the recipes you can learn with tribal... I have been a 300 tribal for a while and have most of them, except the new DM recipes.

Devilsaur legs and gauntlets(THIS IS A 2 PIECE SET)---> some of the best armor for rogues... better than elemental stormshroud for "most" rogues.

Ironfeather breastplate and shoulders (THIS IS A 2 PIECE SET)---> some of the best armor for casting druids till Wildheart...

Frostsaber boots, gloves, chest, and legs---> gives resist to frost and shadow.

Chimeric boots, gloves, chest, and legs---> gives resist to arcane and nature.

Warbear woolies and harnes---> gives great strength and stamina, but kinda disappointing armor.... still good for a feral set for druids

Hide of the Wild---> This is an awesome epic cloak that takes a LOT of hard to get/expensive mats... increases healing and gives int and stam.... perfect for any healer.

Corehound boots---> Hard to get recipe from MC.... gives agility, stam, and 24 fire resist making them awesome boots for rogues in MC/Onyxia

Wolfshead Helm---> useless helm unless you are a hardcore feral druid.

Well I think that is about it.... pretty much if youa re looking to make money you will pump out devilsaur items as there are an icredibly high number of rogues and almost all of them want a devil set.&nbsp You can also make some money making the ironfeather set because the drop on the breast is a pain not too many people have it so you can sell a set or two a week on a good pop server.&nbsp Hope this answers most of the questions that I know I had.&nbsp Feel free to add any armor I forgot which i am sure I forgot a few.

This does not require level 46. I can't confirm the minimum but 40 (or even 35?) would make sense. I completed this quest at level 43.

The quest -is- unavailable until you complete all the quests from the fellow in Feathermoon Stronghold (re: Wild Leather), including taking the letter to Darnassus.

&nbsp &nbsp &nbsp To change from tribal to elemental, talk to your specialist and pay the 50g to unlearn the specialty. Then fly to Tanaris and run to steemwheedle port to the house at 65,21. Theres a book on the table there called "Soothsaying For Idiots".
&nbsp &nbsp &nbsp Read the book and choose your new specialty, then go talk to your new trainer.&nbsp :)

You must complete the wicked leatherworking quests in feathermoon before you can even start tribal.
