I have a 95 hunter, and I SWEAR by the historian vocation for her. Once you get into the 20s, you'll be able to use bow chants/oils, two things I can't play my hunter without. Bow chants and oils make you hit harder (bow chants reduce enemy skill damage mits and light/fire oil will give your arrows light/fire damage so you're not using common). Also, you'll be able to craft morale and power potions, focus potions, and hunter books (tome of the wind-rider, etc). Historian definitely.
