Hi I`ve been having problem with my SW each time i complete a quest my DS points are only at around 20 points, I get more when I do the DS options and my alighnment is on darkside. Is that normal or am I doing Something wrong???

The more you advance, the bigger the gain will be. And don't forget that you *also* get DS points (assuming your toggle thing is on dark) for killing foes, but you never see these points being given to you. (Yes, that means that Jedi can earn LS points by slaughtering refugees.)
