Note the reason I suggested Baroness was not for her healing, but for her extra turn granting. She packs a decent punch especially for her power move and grants extra turns.. that was the imperative thing (Also wears Destiny talismans so it makes her more difficult to kill -- although it can happen due to the buff stealing enemies in GASV).

If you have another character which grants allies extra turns that can help the baroness jsut seems to do it without fail hen she uses her Power ability.
