Yeah, not sure on the difficulty to implement, but would be nice. PDCs acting as they are now - no overheat - does potentially render that useless. Not so much if there were some % chance to intercept - I have noted current missile terminal runs on some larger ships do weave as they get closer to the target. This could start earlier to help with the whole "PDCs just spam fire one direction".
Instead of focusing on straight "range" for missiles, rolled values could focus on "flight-time", and "acceleration".
