I got the Krondi 2 weeks ago and its a monster. Being able to citadel BB's is a huge shocker for me. The Musashi is great but turns like a truck and you cant move the turrets at all. Its faster to turn the ship to aim. It depends on your play style. If you are aggressive go russian battle cruiser all the way. If you prefer to spend the first 2 mins reversing to the back of the map then an IJN BB is for you
