Your kingdom can only create dragons to other kingdoms between 80% and 125% of your net worth! While you need 50% NW to get your win...
in my opinion, at war, there should not be range caps.
If a KD is stubborn enough to keep fighting and hold the 51% NW as long as possible...
Why couldn't the winning kingdom use their earned econ advantage to put an end to the conflict with a dragon?
Maybe there is a valuable reason to keep those boundaries in place but I can't find it myself. War is War.. that's my 2 cents
