Starvation victims abroad need help NOW!

It's not exactly unbalanced. It's usually a lot easier to replace the army than population.
The main danger would be getting locked into a cycle - as the population decreases, the supply decreases, next turn there's an even bigger shortfall....

I'm almost afraid to ask, but what is unbalanced that needs to be fixed?

[Archonsod]

Nobody said anything was unbalanced and needed to be fixed.

The supply requirement is a balancing factor. The larger the army, the more supplies it consumes. Remove this fact, and the game basically comes down to whoever can recruit the most troops the quickest.

If this were altered, then something would need to replace it. My point was that having the army consume population if it were undersupplied would be just as balancing - Unless you had a death dominion (who don't usually need supplies anyway) you couldn't leave the army in any friendly province without it damaging yourself, and you'd need to quickly move it out of conquered provinces otherwise they'd become worthless.
