Ordinarily what you'd do is: you'd have one "race" with bronze armor and another "race" with studded ice. It's kind of a book-keeping headache.
It isn't going to be "perfect" but it is intended to be *scrupulous* - meaning, if you spend more points on troops, *all* of your troops get better (cheaper, if nothing else.) Some nations get units which are bad-*** and don't pay extra gold for the privilege - how do I balance that? etc. etc.
The idea is that if you have one super-infantryman and a bunch of crap, you won't ever recruit the crap anyway, so it's free.
But obviously there need to be exceptions for this - for example, archers and infantrymen really do fulfill different roles, and some nations should have superior archers vs. other nations which don't.
Spearmen and swordsmen are *supposed* to fulfill different roles, but the extent to which they do so is not what might be desired.
So I'm thinking carefully about it
