I think one way to improve gameplay by making it more challenging is to not allow divisions to be instantly reinforced. The organization penalty and supply cost is not nearly enough in my opinion. Perhaps if a division can only increase it's strength by a little bit every day, it could balance it a little better.
Therefore, if a division is taken down to 1 strength and wins a battle, you cannot instantly reinforce them, wait a few days for org to go back to max and keep invading... you'd have to let them reinforce themselves for a month or so- which is still much faster than building a whole new division, yet not so fast that you suffer no attrition from wars besides a few meaningless supply less.
