Actually... how do the cavalry weapons work? I've just remembered the cataphracts used the mace as a secondary weapon and I'm sure swords and stuff were used by other types. You've mentioned the mace and sword aren't shown in those profiles, which implies that they are actually accounted for in battles. Is this the case?
We could give a flat attack value to the primary weapon otherwise. The kontos/xyston could be 14, any other lance 12, spears and such 9 and swords 11 or something daft like that. I have an idea, why don't I go check myself?
Edit: Hmmm, think I'll let you get back before I go any further. I suspect you've combined the mace and bow together for the primary weapon, yeah?
