So you want a character with at least avg Defence and good support abilities and awesome damage potential. Dark side tendencies on the Pub side and with Blasters pref. Seeing how you said no to the big weapons that rules out the Commando and you should go Merc. They are independent anyways so the fact that they are CURRENTLY allied with the Empire shouldn't bother you. It has most of the things you ask for. Plus if I am right you are yet another Fandalorian so...
. You get to shoot a guy and Heal him xD
