After every victory in war, your villagers celebrate! As a result builders become motivated and building time is accelerated by 1 day or a few hours. Same could apply for laboratory upgrades perhaps, but builders makes more sense.
I think this would be a sweet idea and it provides further meaning and incentive to war. You can even have builders get demotivated although that idea is quite rigid. But the initial idea would be a great addition i think!
Opinions?
