If we check passives for Alchemy and Provisioning, there are neat passives, which give "global" bonuses:
Alchemy is OP at this:
Medicinal Use,
Snakeblood.
Provisioning have too, but maybe not so boosting like those from Alchemy:
Connoisseur,
Gourmand.
The other 4 should have something similar. Maybe increased durability for Blacksmithing/Clothing/Woodworking and increased charge for Enchanting.
What do you think about?
Thanks
