@Chacmool:
Did you ever thought about an activation of Minors via paying money?
That’s actually a pretty good idea. I’m more in favor of aligning Bulgaria with Germany, but paying to activate it is basically an equivalent of a war loan (e.g. 4 IPCs). And in my when-I-have-time house rules, Bulgaria would operate as a country piggybacking on a larger CP power, but with an economy unto itself. So the activation is basically like a significant cash infusion into an otherwise small economy.
I can’t see Romania being aligned with France, even though it recieved substantial help later in the war. It simply had more natural political ties with Russia, and Russia increasingly had to assist the Romanians directly once the Romanian invasion turned into a rout. So, yes, then after that point, the French assistance becomes more important.
I would consider operating Romania just as Bulgaria (attaching it to a larger country but with its own economy). Bulgaria and Romania were not too far off in the amount of troops mobilized, and if not equal, the Bulgarian troops made up for it in quality. Though I must say the Romanians had improved greatly by the end of the war.
I have early-war British HaT pieces that will stand in for Bulgarians (field caps are pretty similar at that scale), and A&A 40 can provide Frenchmen in Adrian helmets posing as Romanians (accents will give them away).
But I think it would only fair to boast the value of Bulgarian and/or Romania by an IPC just to facilitate their economy. They really shouldn’t be able to reinforce with more than a corps/infantry per turn.
