What I would like would there be a strong focus on using the materials that you have, with production choices taking presidence over technological choices.
For example, as Germany, do you try and produce the Panther, in small numbers, or rely on the Mark IV which will be produced in greater numbers? It isn't simply getting the Panther and using as the superior war winning strategy, but make a conscious choice that I have technology, do I apply it? It wasn't that the Germans had a special tank that nobody else could have (the British and Americans also had their equivalents), but was a production decision (Allies relied on the Sherman in mass numbers, Germans went for the Panther in smaller numbers). However, in the HoI1 or HoI2 universe, the idea of keeping the Sherman in production would be luduicrous, given that technology always prevailed.
