Good discussion.
After reading it, I'm going to make a few corps that will be 4 infantry divisions of 2xInf +2xArt. I always have trouble attacking into France's wooded northeast. I think this might be a good work-around.
Normally as Germany I'm religiously 2xInf +1xArt. I'll still remain that way.
But now that the AI can invade next to ports, figuring out how to defend the coast is important, and I'm wondering if I should do AA or AT for my units defending a port.
In 1.2, I would build 3xGAR+ 1xArt, and I think I still might do this, because it's cheap, and can hold a province for a bit to allow reinforcements.
