About the Indicator I explained earlier. It’s big, and how big it is? Big enough to annoy you during the battle.
Mutsu armor is trash, even Nassau can citadel her. Gun is garbage, 1.8 sigma? More like 1.5+1. Terrible AP shell, 9 km and I could not guarantee a citadel hit on an inactive bot New York. 58400 hp will not save you from anything. Useless torpedoes , you use those, you are inviting BBs to citadel you.
