I was surprised as Germany after inflicting major defeats on Russia and France in one turn, that all Entente powers lost 3 NW points for each defeat, a total of 6 for the turn. Both Germany and Austria gained 6 points.
Would a major defeat for Russia really effect France and Britain that badly, and vice versa? Verdun may nearly have broken the French army, but had nothing like the effect in Britain of tens of thousands of names filling the newspapers after the Somme, for instance.
Would -3 for the country or countries whose troops were involved, -1 for allies whose troops were not involved (and the other way round for the victors) be more realistic?
