Should have a small amount of crafting added to them. For example;
Mining- Can create both sharpening and weighted stones. Also small figurines(provide minor magical effects like healing, taunting, scaring, etc within the open world).
Herbalism- Can create healing potions, anti-venom, remove bleed and disease items. Also make bandages.
Skinning(rename to Survival)- Can create special beast lures, simple jerky(eat on the move), torches(helps to see invisible creatures sooner), snare/traps(to help catch non-rare/elite battle pets).
Fishing- Can create fish lures(many fish eat other fish), nets(get all the fish out of the pool at once), and sashimi(can provide bonus effects). Not so much create but discover message in a bottle quests.
