What I personally don't like is the way doctrines are set up to basically force the player and AI to pick 2 ship types. Every navy used most of the ship types historically for a reason, yet the game encourages you to pick a single screen and capital ship to focus on rather than use all ship types. There's a reason why Germany's Plan Z included carriers and destroyers, and why Stalin's 1936 build plan included ships of every class defined in the naval treaties, rather than just subs or carriers and light cruisers. The thinking was that each ship type has a role it excels in, and you need ships of every type to be effective. None of that is reflected in the game outside of the OOBs.
If anyone's interested in how navies were actually used and how each country planned to build up their navies before the war, check out the navy info thread in my signature.
