I have a guy on one of my secondary systems that insists on giving me XP
... he sent 375 destroyers the first time and 170 the second time to a planet that I was sitting on waiting for my culture to go up
... I originally had just 18 destroyers sitting there and he wiped those out so I sent a fleet worth about 1900CV and took him out
... that same fleet was waiting for him when he came back
Muhahahaha
