I'm assuming all classes will truly have equal numbers of SA/FG skills. Give us an option similar to the "Lock" skill function - we have 4 slots. 2 for FG and 2 for SA. We can then hover over a skill and in 2 corners we have an icon for FG and an icon for SA. We can then select which skills get FG and which get SA. I suppose we should only make skills which previously had SA/FG available to adjust. You should make changing these options require a memory fragment and a skill instructor.
