Best character out of galactic war shipment?

Luminara is a best bet because she has good turn based heal, hits hard, has nuke with ability block, easier to starred since you can farm her on a mission coupled with galactic war shipment and you can never go wrong with another healer for your team in galactic war battles.
Though if you already have Bariss or old Daka and thinking you dont need another healer, you can go for any other character you want.
