Marat battleship need to be 7.0

Marat battleship should be 7.0 as like kommuna.
This is the same battleship with same armor.
But with a little bit less AA. But as the same firepower.

This Marat will fight agaisnt light cruisers that they will be erased in the first 3 min of matchs.
its like poltava & marya, they should be 7.0
