This game has been designed to be a perfect playground for roleplay, the devs have stated this many times, why would they then go and make this part of the game only work for people who roleplay in ONE way?
Simple answer, they wouldn't and they didn't.
Now I may role play one character I have as a bloodthirsty villian, a true child of the Empire. Despising the Rebels, filled with hatred of them and hunting them down and exterminating every last one of them.
However I may roleplay my character on another server as a independent businessman, looking after his home, tending his arrangement of potted plants, pillar of the local community, not an evil or spiteful bone in his chubby body.
I can roleplay anyway I choose, it's the beauty of it all. I can be in-game who I'm not, or who I am, or who I want to be, or who I'd never ever want to be, in RL.
It's what you do, mechanics like, that affect unlocking FS, not how you do it, being an evil imperial or a happy loving gardener.
Play the way YOU WANT to play, not the way you THINK you need to play.
