Hello, i find pretty annoying that there is no french army in the battle of france, or dutch army in rotterdam. I can understand why there are not here, for practical reasons.
But why not add customisation for the allies, with french and dutch features ? It seems easy. Polish features could be good too, they were a lot in the allies armies.
As french, don't see french army in battle of france really hurt me. They fought, dispite what stupid stereotype could say. Germans were just better at that moment.
