While I agree Games Design is 'hard' the fact that they obviously have no meaningful probability model behind the system is pretty sad. It's far from impossible to build a computer algorithm that links relevant probability matrices as a way to validate points values relative to abilities. After all we're only dealing with a 10 scale attribute system and d6's. Plus the core model only has to be built one time. Play testing would essentially be used to validate the model.
The fact that it isn't done speaks to them not having any interest if things have any relative balance at all. Probably because imbalance is more profitable then true balance. It's also pretty telling that in lieu of addressing real issues the current design philosophy appears to be 'add increasing layers of randomness' to offset any inherently poor design elements.
