Maybe it's just me, but I've found that I'd rather have more control over skill groups than the rules allow at creation. So I've been playing with this idea: making it interchangable to turn 5 skill points into 2 points of skill group.
If you have Skills at C and 28/2, you could just get 33 skill points, or you can get 23/4, or 18/6, or 13/8, etc.
Anyone try anything like this? How well does it work out?
