Professions

Herbalism

early gold while levelling. Wowhead singles out Druids (Travel Form, Prowl) and pet classes, whose pets hold a mob while they pick.

Mining

gold with no money needed to start (Wowhead); no racial affects it, and Druids, Hunters and Warlocks escape mobs most easily.

Skinning

semi-passive gold from beasts you're killing anyway (Wowhead), especially leather and mail wearers supplying Leatherworking.

Alchemy

consumables you will use or sell repeatedly, for any class; dozens of new low-level recipes make it worth taking while levelling (Wowhead).

Blacksmithing

specific self-crafted mail and plate, mainly for Warriors and Paladins, rather than a promised gold income (ForeverDB).

Enchanting

access to enchants and early crafts, especially wands for Mages, Priests and Warlocks; don't count on Tailoring to finance it.

262 recipes · 62 new

Engineering

gadgets and tools you expect to use, and guns for Warriors, Hunters and Rogues; check each item's use requirement first.

Leatherworking

self-crafted upgrades while levelling for Druids, Hunters, Rogues and Shamans, when the specific pieces justify the cost (Icy Veins).

Tailoring

cloth casters (Mages, Priests, Warlocks) filling weak slots with their own crafts while levelling, plus bags; start with a few useful pieces.

Cooking

every character: it's secondary, costs no slot, most of its food adds 5% kill experience, and cooks build the campfire camping hangs on.

First Aid

every character, most of all those who can't heal themselves (Wowhead); it's secondary, and in Forever it makes the healing potions.

Fishing

anyone; it's secondary and needs no materials. Wowhead picks out Shamans (Far Sight, Water Walking) and Hunters (raw fish feeds pets).
