VCO and WO both have the two biggest/most active "night time" fleets and BOTH complain there is no one for them to attack at those hours. But instead of attacking each other and having some decent battles, they choose to work together to multi flip nations that they assume cannot fill the port battles. I mean they're already targeting what they see to be easy battles yet still feel the need to multi-flip.
I agree with what you say about giving the US chance to put up a defence but that is not what these guys want
