Dear developers!
Many battleship user have to face with a huge problem, when they go into a battle, mainly in higher tiers (8 and above, caused by the repai prices). Crusers (not just Moskva or Hindenburg classes!) and sometimes destroyers can make citadel hits on them (not just on the modern all or nothing ships), but in reality their armour piercing shells could not scratch the battleships armour belts, or armoured deck(s). If you will decrease the battleships armour protection, you will make free hp pools and frags from these capitalsips. Therefore battleship users try to avoid the close range combats to save their hp, however many of this kind of ships is a typically designed for close combats. If your goal is that to make battleship users more aggressive, you have to increase the battleships survivability, and they will fight as they have to. I think the main problem in the game, that escort ships (cruisers and destroyers) leave the capital ships (battleships, battlecruiser and fleet carriers) alone with enemy fleet, and they can not escape from the situation, or fight back effectively in a 4-9 to 1 battle.
