You guys are too much into maths….
Even at 12, UK will buy Cruisers. Why? Even if Destroyers are superior for defense/offensve (naval), Cruiser has the ability of hitting the ground when dropping troops.
Tanks @ 6ipc. Means you can’t do super stacks of tanks that easily. Means tanks become valuable (which they should be)
Also, Tanks being a ground unit will reinforce a territory you conquer. You can’t land planes on them, remember?
Technically speaking, Carriers are really really expensive. You will have to build them to control the sea.
About tactical bombers. I’m still not sure how they function. The word “bomber” could be misleading. But if this type of plane can SBR, then it is good (range could be an issue). Otherwise, it must have some sort of ability. (Maybe the boost on armor will be enough to justify their purchase)
One thing is sure, this game will be completly new. Air bases, naval bases, new units, new costs, bigger maps… The game will change. So all these discussions on the costs (Without the actual map) seem to me pointless.
