Well you know these are going to show up right after Deluxe shows up.
But id place all these units on D12 at that point so that each nation has different values for its ships anyway.
Also light and heavy cruisers are more accurate, because only really Uk and Germany had Battlecruisers, while the Alaska class battleship was a battlecruiser, and most of the British design japanese battleships were in fact battlecruisers. However this class is far less in numbers than either light or heavy cruisers.
Id give the battlecruisers a 3 attack and 2 defence, but moves 3 and takes 2 hits cost 15-16
Heavy cruisers at 3/3/2 take 2 hits cost 12-14
Light cruisers 2/3/2/ take one hit cost 10-12
Destroyers 2/2/2 one hit cost 8-10
