anything really just make sure you have the best professions, as far as leveling is concerned, huner/DK is the easiest and quickest to 100 so that might be something to consider
ayy, yeah thats the 2 i came down too my self, i just have a hard time choosing.. like i wanna farm the BoE 665 items in WoD and know sometime there are +5 mobs that hurt, just not sure if hunters can deal with it,. like a blood dk would.
I'd probably go DK mate, depends if you're set on farming higher level mobs for better loot or lower level mobs but more of them. DK = more utility and survivability or hunter for quicker clear times.
Pick Tailoring next to skinning, you might want to mix up skinning with occasional cloth farming. Passive bonus from Tailoring makes a substantial difference
