Since even in WoW I didn't pay attention to my skills and their proper use, I don't think I'm qualified to offer any insight.
There is a viseral feeling about swinging a lightsaber though. Granted, I'm still in the newb area so all I get is a jedi whiffle bat. I'm just button mashing right now. But I think I like running up and hitting things. Made a smuggler, but the finding cover and shooting hasn't grabbed me yet.
I was curious, so I made a sith imperial agent. I honestly don't think I can play that faction. You have to be a dick aaaaall the time if you want to raise your dark side points. I don't think I have it in me.
