I would like to see an anti-fighter weapon similar to the automated PD turrets that only target missiles. Here’s what I came up with: the Fighter Scrambler. Sort of a mini-EMP that can only target fighters. The pulse duration is extremely brief, and shuts down the fighters ability to a) fire weapons and b) turn. Essentially, for the half second or however long the pulse lasts, the fighter moves in a straight line on whatever heading it had when it was scrambled. consider it a Guidance Scrambler beam that wrads off fighters instead of missiles. Give it a suitably low % chance of affecting the targeted fighter and a high rate of fire, and you have a halfway decent low-level defense against fighters for large cruisers - scrambled fighters would have a tendency to fly back out of the shield bubble before they came back online.
Very rough concept; mostly came to mind because that way a cruiser that doesn’t “engage” fighters still has an active form of defense.
