one thing you can also do is get AMM that outranges them, or a slightly bigger, cheap Anti-Ship Missile, and throw a couple of thousands of them at the enemy. big ball of size1/size 2 box launchers, some 5 million km range, and some hard to hit missiles should do the trick. if everything goes right, they either waste 3 times as many missiles as you do, or eventually get their PD overwhelmed, and start losing ships. never quite faced a AMM storm quite that violent though, not on C#.
