The slow North Carolina AP shells are a known thing, but there are folks that learn them and excel. My frustration was more that the 6 barrels lead to some really awkward salvos whereas the North Carolina has 9 guns to make it more likely the holes are more filled in. Kearsarge has NC guns, but she has 12 of them AND the dispersion upgrade in Slot 6.
When Nebraska's guns connected, they were Battleship shells. They just didn't connect as often as I would have preferred.
