Started a Sith Marauder, DPS mainly but still low enough (17) to spec off-tank if needed. Currently Carnage tree(?) (Middle tree), pumping points in off-hand damage and Ward/Cloak/Area damage mitigation). Pumping high loads of Endurance/Strength (mostly endurance for off-tanking) since her offensive moves are pretty much Tank-Hater aggro steal
Using the item mods that grant END over STR (Guardian/Patron) rather than Might mods. SO far it's working great while still dealing loads of damage (of course Vette is brutal helpful when soloing.. hehe).
