Have decided to firm up my system knowledge, and have been going through the Axioms articles. Axioms 2 gives rules for beastman custom classes. I think I understand the custom classes rules well enough that I should be able to understand the beastman custom class rules, but there's something I don't understand, and I'll use the Orc custom class as an example.
If you get all the Orc custom powers from even just having Orc 0, why would you take more points in Orc? I understand it stacks with points in Fighter, but it appears to cost more than points in Fighter (in terms of XP cost), and extra points in Fighter would get you extra stuff. So what do more points in Orc get you?
