Underdog and I tried out a bunch of different combinations one time before I moved away from where I went to high school. ISD1 vs. MonCal, no fighters: Imp victory. ISD1 (I think. It might have been ISD2) vs. Dauntless, no fighters: very even fight, but Imps win. Both of these battles with fighters result in a Rebel victory. Bulwarks withought fighters lose to SSD's withought fighters, but with fighters in the battle, Bulwarks win. We found that in the capital ship only battles, the Imps would win more often, but as soon as fighters showed up, the Imps often got their asses handed to them.
