should I grind for the USS Portland? (serious only, and yes I have a premium blue water vessel )
Tbh, I must tell you that every Washington treaty cruiser in the US is a free RP box.
The protection of the Ammo racks is nil, and whether this is Portland, Northampton, or Pensacola, your ship will lose combat power by simply shotting the ammo racks under the main guns.
With Atlanta being the absolute meta, there is not much point in using US CA except as a personal interest.
