Each one also gets Adaptability.
So you're going to be the king at blocking with your 4 large base ships with barrel roll. Is blocking a triple U-Boat list and beating it by just out-turreting it feasible? What about against aces? You can block them easymode but with 2 attack you might still have trouble pushing damage through.
Against low agility stuff your 2 attack can handle it.
I already have 3 of these things, thinking of just ebaying a 4th for $16.
