I have a suggestion/idea to stop the porking of the rook (or not used bases). Why not have a three front war?
Bish: American and British planes.
Knights: German or Japanese (which ever setup is running)
Rook: Russian planes.
Except for early war BOB, Russia was involved on both fronts so why not have Russian planes available?
I'm not a CM, but if you can't totally disable the odd bases why not use them and stop the map porking?
Just an Idea, but it may also bring more targets into the arena:t
