All the work on AI seem great and I look forward too it... as an old fellow AI programmer I know how difficult it can be and how one tiny thing can leave a ripple effect you never expected.
I have not seen anything mentioned about the Air AI in the patch notes or diskussions, I do think this could need some love too. The AI seem to use the Air war fine while they have one enemy and one front but once the big war breaks out the AI often seem to hide away their air wings in strange places. Like Germany and Italy sending their entire air fleet to Japan while Japan sending theirs to Europe. All sitting in a few large airbases doing almost nothing.
I'm not sure if this is just some random things in my games or not, but it seems as if Germany do have problem using its air-force against the Soviets as well as defending against allied bombings at the same time, it seems to get a bit confused.
Would be nice to hear if any work have gone into how the AI handles its air-wings?
