Well, I stack the hell out of France, and I imagine a lot of others do to. So basically the ways to come at my Germany is via Baltic/States/Poland, or Bulgaria/Balkans, or Northwestern Europe if the Allies have alot of troops ready for a series of landings. Of these options, Poland is obviously the most efficient…it’s just kind of ahistorical.
I guess what I would like to see in the next version is France/Northwestern Europe divided into 3 zones for more fluidity there…and Italy divided into two northern and southern zones so its harder for Germany to help stack it. If Italy is 2 zones, then it becomes more logical that the Allies would attack there first. This would draw away German reserves, and hence open up the opportunity to land in France.
Meanwhile, forbid the Allies from landing in Arch/Leningrad, and make it much harder for the Allies to clear the Baltic and eventually land there. Finally I think it would be cool if Balkans was divided into Greece and Yugo for more action in that theatre.
