Let's list some of the major things that annoyed in the naval system in earlier games.
1. Cruiser spam. Due to ships battles implementation, crowds of cruisers could roflstomp battleships with ease. The ships need so form of armor mechanic, so that building bigger ships is a worthwhile investment as long as you have air superiority. BBs and CVs are not that numberous, so they could even benefit from some more detailed damage system than a simple strength bar.
2. Subs. From overpowered to underpowered, from battlefleet killers to waste of IC, the subs have never quite got proper "Battle of Atlantic" representation. As convoys are a resource, rather than actual units, how about turning subs unto "resources", build like convoys? It would allow a more macromanagement approach of assigning a number of subs to and area of the ocean to raid and automatically fill up casualties.
