So I have 8 chars that I have at level 100. I have crafting professions maxed out on 7 of them with gathering on a 8th. So my question is, what professions should I have on them all to make the most gold? I have Inns on all of them, barns and salvage yards on 7 of them so pumping out blood like crazy. Combining the blood with the crafting materials seems to be fairly profitable so I've been sticking with that. So any recommendations would be greatly appreciated.

Heres what I have split up into each char:

Skinning and Herbalism

Jewelcrafting and Enchanting (My main)

Leatherworking and Alchemy

Leatherworking and Jewelcrafting

Blacksmithing and Engineering

Tailoring and Enchanting

Blacksmithing and Inscription

Inscription and Engineering

I don't mind switching up some if needed. Ive always wanted to have Engineering on my main because of the cool shit they get. I just don't know about the rest of even if gathering is needed since i so rarely use it. I only got it for felblight and that's stupid easy to get these days.

Edit: for more information and spelling because drunk >.<
