i had a uk bb crew i went with the revenge its 1 of the best ships to use in blitzkrieg
the queen elizabeth has alot of aa slots and it can do small amount of damage to a bb who does not see you but most of the times you get outranged
the king of george 5 i dont know same as the prince of wales remodel but if you can get it to block shot and armor whore or speed whore with it you can do alot of damage
if you wanna do a cv crew go with usn or any other nation as the uk fighter and divebomber planes suck their torpedo bombers are good but dont go cv with uk
