I've played around with each class and tried different set-ups, and I noticed one thing about rangers... They have very few exclusively-beneficial accessories, and have no means of healing themselves besides potions. Mages get the Spectre armor, and Fighters get the Vampire Knives. Rangers get nothing. Maybe a craftable ammo that heals a portion of damage back? I don't know. They just need a little more love, in my opinion.
