I kind of wish the AI would go with mixed design ships sometimes. Instead of missiles ships that have all their fire controls a particular resolution, have them have both an anti-ship and an anti-fighter fire control. And missile ships should have at least one beam weapon so that they can't just be ignored after they run out of missiles. They might be slightly less efficient that way, but they would also be less vulnerable to being picked apart.
There is a PARTICULAR tactic I use that beam fighter PD is uniquely effective at:
I was not sure if my point defense was capable of stopping all the enemy missiles, but I knew that their anti-ship missiles would fire on my 1,000 ton missile boats before they fired on my 500 ton railgun fighters. So I tested the enemy missiles by flying in with just one of my missile boats, and all of my railgun fighters. I figured that the enemy might go for massive overkill, in which case, I would be out one missile boat, but I could still run the enemy out of missiles, or it would fire what it considered a reasonable amount of missiles to kill a 1,000 ton missile boat, and my fighters would easily be able to deal with it, and I would just run the enemy out of missiles that way.
It didn't work to deal with AMM spam, because the enemy would potentially fire at everybody, but if I didn't go too deep into their AMM range, I could just duck back OUT of range once I detected enemy missiles, and only have to deal with a few volleys.
