I recently got the CBT, and Imedieatly threw myself at the BIG ships, and i must say that i have made the same mistake in WOT, thinking that heavy tanks, were the absolute rulers of the field.
in World of Warship, Battleships are not invinsible, they are slow and hard to turn, however packing a serious punch, but not the rulers of the sea.
I have the Kongo now, which is my all time favorite. The Kawachi and Myogi, had their strengths and weaknesses,
The Kongo is the best AA fitted ship of its entire tier, and those are very much needed when dealing with Aircraft Carriers.
its Main guns are packing a good punch, but very inaccurate at the long ranges, decent reload time for a Battleship, but do not fire at when turning, unless they are within 6-8 km.
Armor: not much, plenty of Hp, but that is just about it im afraid,
i can not wait to get my hand on the Fuso
