After playing the game and the cheat menu for a while, I noticed a drastic issue regarding the heavy cruisers implemented into this game, which is their lack of a salvo function when in groups, and barely a use of their main armament. They seem to only use two guns from one turret when it is multiple Heavy cruisers, and it is like the other guns are decorations. If you look at the first picture, you can see some two shot barrages, but this is coming from about 30 ships, each with six frontal guns (the one I zoomed in on has one turret knocked out, but it still doesn't explain the lack of the third shell in a salvo, or the overall lack of coordinated salvos from the cruisers) . Another thing is that ships seem to give up if there are too many targets.
