Yeah but I have two very decent archers that are perfectly capable of murdering them from behind my front line, I don't need to expose a melee character in this way. It's a suboptimal strategy given my party setup.Barbarians greatest strength is acting as a skirmisher going after preferably isolated squishies charging all over the battlefield. If you are not above using mods, getting EA, CotW, etc. makes her into an Invulnerable Rager with 19 strength and access to Superstition and Witch Hunter. With that she makes mince meat out of casters easily and thanks to decent DR and high HP archers are not much of a challenge either. Bind dangerous melees to the tank, go around the main pulk and start murdering squishies. That works even with Amiri from the base game.
Additionally, I already have a very capable melee character who is basically immune to damage and has such high saves that he walks through spells, poison, and so on unscathed, so if necessary he can go kill such targets himself, while drawing lots of attention that way at the same time (which is his job).
Invulnerable Rager would help but it wouldn't prevent her durability being a limited resource (tanking by HP) as opposed to an efficient, long-lasting resource (tanking by high AC).
She can work as a tank with Guarded Stance then get 1 point in dex for Dodge, and improve her defenses through Toughness, 6 more DR from rage powers, Protect Vitals, 3 Mobility for +1 AC from fighting defensively, Shield and Armor focus, use a normal bastard sword and shield switching to her big one when she gets no attention or when on clean up duty. Get her the best medium armor and any item to giver her enough dex for the armor she wears, buff with Cats's Grace if necessary.
