I think our discussions are going back and forth, and the bottom line is:
1). Playing style (some people like to run allied SBR campaigns, some like the Russia rush with Germany, etc)
2). the game situation dictates if an IC is a good move for Germany:
Can they take Karelia/Caucasus?
Is USA triple teaming Europe?
Will Germany have a 35+ income for several rounds?
3). Thus far, there is no one prescribed ‘best’ move for either the Axis nor the Allies. Therefor, there can be no absolutes about specific moves.
excellent points! everything is fluid and the meta game becomes critical for seizing the initiative on your opponent.
