Supplies - Sending an army that will not starve ?

[Sombre]

The current supply model doesn't really make sense anyway, which is part of the justification for changing things to fit better gameplay.

Mammoths require 5 supplies, Caelians require 2. So three Caelians need more supplies than a mammoth? Caelins need the supplies of two humans, or a knight? Big eaters those Caelians, considering they're lighter and weaker than humans.

And I know people will say "But supplies don't just mean food, they mean all kinds of logistical requirements!" Ok then, explain why creatures that need not eat don't need any supplies, regardless of size.

It's fun to hear thematic arguments though because it's always possible to argue anything either way.
