In the simulation with individual fighters, when the clans had their own fighters the fighters we focused down first. Then, with the escort gone, the ai moved into the rear arc and shot that up, with the easiest to hit mods. The fighter stack sometimes hit other out of control fighters but only a couple of times. With normal init, the warship just had to take it. With advanced init, sometimes the warship would win and engage with better arcs. But, normally all warships have to move first so this wasnt common.
As for the capital fighter survivability, I agree that if you are modeling 10 different 10 damage guns, then it makes sense that the capital fighter would distribute it. But im talking about 160 damage bays from the warship. Those always hit one spot, and each hit should be a fighter kill. But with capital fighters its not, making fighters even better versus warships. Thats just one of the things that made capital fighters, and capital squadrons especially, way deadlier to warships then regular rules.
