Last weekend my opponent conceded the campaign, and I couldn't really see a way to argue his points. Going into what became the final round (round three), both of his fleets had one win and one loss each while one of my fleets had two wins and the other was at two losses (but only an Arquitens and a TIE Fighter were scarred). I then tabled him in both games, losing a single Victory I and two Arquitens. Also some squadrons, but nothing I can't repair or field scarred. Basically I would have been in good shape going into the next round. My opponent was so battered that he couldn't even afford to clear the scars from all of his ships, and I was about to gain a major resource advantage thanks to bases. In short, I would almost certainly have smashed him in at least one of the battles in the next round, most likely knocking 100 or so points out of at least one of his fleets. I would have had plenty of points to repair any similar damage to my own fleets.
What I'm looking for is a way to mitigate the snowball effect. I understand that if he plays very well he could minimize damage or do a Show of Force (we both used Imperial units, but I was the "Rebels") to regain some resources. But he'd be fighting at a disadvantage even if I didn't take advantage of the situation to seize Corellia. I enjoyed the sense of progression but a lot of that is lost when we hit a point where it was clear who was going to win. SO I'm looking for a house rule that prevents the situation from getting too one-sided while still rewarding me for killing ships.
My first thought is to leave everything as-is, except that scarred units don't permanently die if destroyed. So there's still a drawback to taking losses, but not one that can cripple a fleet entirely. While it is nicely dramatic that our campaign ended after one heroic victory by the "Rebels" it did create a situation that made continuing look like an unpleasant slog for my opponent, and I think this rule would prevent that without making kills feel pointless. But we've only done one campaign so I'm interested in thoughts and opinions.
