Re: "Shallow" Purchases
My COM scores are usually set from an early point. I'm pretty visual when concieving the character, and throwing a couple extra points in there can throw everything off. Likewise INT. I find that when I have a few extra points they usually end up as Knowledge Skills, Enhanced Senses, or minor movement enhancers.
Then, once that is decided, I look at the entire thing as a whole, editing and revamping, basing the entire character omn that minor purchase, pumping it up, losing points elewhere, having a few points left over...and the whole thing begins again.
