Crimson Longinus
Legend
Barbarian of course could be a subclass of the fighter, and in a game with significantly fewer classes it should be. But in current style where there are crazy number of caster classes I really wouldn't want to get rid of one of the few martial ones. And also I think the distinction between a skilled warrior relying on state of the art military equipment (such as plate armour) and a primal one that relies on fury and perhaps the aid of the spirits seems like rather good way to make the split.
