Not sure what anyone else will think of this, but I wanted to mention that while I was reading through this, I found the thought of Voluntary Flaws ridiculous. If you drop statistics, you should get something for that. If you don't want it to be one to one, you could always make the drop of 2 points grant a bonus of 1. Or grant an additional feat. But to grant nothing at all in return is just wrong.
I'm also rather disappointed to see the stat purchase missing, not even present as an alternative rule.
