I am also very interested in seeing how fleets with varying compositions do against each other. Yeah, that may not be the focus now, but I am eager to see it. I hope the game really does have that aspect in it, so that a higher quality fleet (better combo of ships and components) could beat what appeared to be a larger fleet. 

Well I can tell you what I have see so far. I took a fleet of two HUGE ships against the Drengins fleet of 3 LARGE ships. He had 2x as much beam fire power against me. However i did have a 2 module carrier in there so upon the fight It was pretty fun. I lost the fighters, the carrier and took 1/4 dmg to the heavy beam ship. Pretty fun actually.
