Umm, I don't mean to be insulting, Iceman, but isnt that pretty much what I suggested in the second last paragraph of my rant.
Anyway, another system might be where you get to asign new stars ( I wonder if they will still have the stars to represent the ability level of a power) after defeating a certain number of enemies or perhaps after completing a task or mission objective. That way some objectives could be optional, not having to be completed but if you do you get force experience. Just a thought.
Genius is limited, unfortunately stupidity is not thus so.
