Dab, my point was simply to demonstrate that from a purely tactical basis, it makes sense to have this ship.
I mean, all your capital ships are being raped by the enemy Battleships.
What do you do?
A) Nothing - Lose
B) Produce more ships! - Probably lose
C) Build a ship better than their Battleship - Probably win
Honestly, it's like WW1 Infantry charges and Machine gun emplacements.
The Infantry are Bretonian Battleships, the Machine guns are Kusari Battleships.
Yes you can throw in the infantry in huge numbers and maybe win but it would be far more efficient to send in a tank or two instead.
That tank is this.
