Yeah but a Barbarian would rarely use a ranged weapon until absolutely necessary, since you need to attack with STR to get all your Rage bonus.Barb and ranger have the same weapons proficiencies; are you referring to a fighting style? A tree barb would certainly work, but a spellcasting tree martial seems pretty decent to me. Hell, with druidic warrior fighting style, you can pick up thorn whip for extra plant-y goodness.
Imagine a Barbarian that turns into the giant tree monster when raging?
