My Smuggler (Scoundrel-Sawbones) is awesome. She's a great medic and is always appreciated in group battles. Heck, I even heal random people when going from A to B on my own missions. I started a Jedi alt when my character was stuck on Taris for a couple days but the moment it as fixed I haven't gone back (I will eventually but no time soon). Plus, she's got some hilarious lines, a cute giggle when certain skills or abilities activate and as others have said, the careful and tactical nature she must be playing in this game is appealing. And yes, I channel my inner Han Solo, Malcolm and Spike when playing. Out to make a few creds but a heart of gold.
I'm the exact same way with the Mass Effect series. I'm a huge champion of the engineer class.
