If I am not interested in healing, should I not even bother with scoundrel? I have a sniper on the imp side so that makes me not want to do gunslinger and go scoundrel for something different. I like the stealth melee, but don't care for healing (and I'm bad at it). On the other hand, dual blasters looks cool.
You can be a DPS scoundrel. Provided you can open from stealth, you're pretty lethal. I have lots of fun with my concealment operative.
