It might be perversely amusing to run an Ashen Empire game with a cheap and low-magic pretender, horrible scales, vast amounts of gold, and no national units to spend it on. (AE... with mercenary fever? Hm.)

But a cap would seem reasonable to me... and if configurable on a per-game basis, a zero cap (on unused dp points turning into anything) would suit the traditionalists while an insanely high cap might lead to Ermorian Mercenary Madness and other strange strategies, which might once in a while suit those looking for more "experimental" games.
