Maybe nuking score penalties wasn't such a good idea? All but one of my characters have been reclassified into Amazons. Even my 5'6" cow-girl character, which by the old system would have an Amazon score of -1.
I've had mixed results, but at least my galotian character's race no longer changes to goo-morph when I switch to plantigrade legs.
I also have another character that is now considered human even though they have different legs, arms, a tail, horns, and genitals so....hit or miss has been my experience so far.
