There is currently a discussion going on in the PtV thread, and I really feel that it would be applicable to OOB/BM.
It’s a problem that the axis can completely evacuate France, and not worry about the allies taking it because it’s a disadvantage. And it’s a problem that the allies don’t want to liberate an allied nation even if they could hold their ground.
If the allies hold 2 french factories in Western Europe, they should be able to produce 6 infantry a round at a minimum. Currently, liberating France prevents that, limiting 2-3 factories to 4-5 infantry at most.
My proposed fix is a +5 NO for France for holding France and Normandy or Southern France. The french earn 7 from Africa, 1 from Syria, and 6 from holding Normandy and France, which gives them a total of 14. You can only buy 4 infantry a turn consistently with this, on 2 factories. With the +5 NO it gives the french 19 so they have the capability to produce 6 Infantry, making it a feasible strategy for the allies to liberate Paris.
I Believe that this idea doesn’t fundamentally change the game too much to be included into BM, and also makes the game more fun for the allies. It makes the western front more dynamic, and could bring the balance a little bit closer to even. This also could make it harder to win in the Europe side, which might bring more action to the Japanese side.
