tailoring probably have the cheapest Obliterum farm.. craft cheap armor (especially if you use recipes with blood of sargeras), then turn them to obliterum and sell it. Or keep crafting the bracers and sell them to people who need for the quest.
Tailoring was cheat in TBC Leatherworking was not near that good... Blacksmith had the weapons, which you could upgrade. That was really nice but still not as good as the god sets of tailoring. You talk like all profs were that good..
