After playing for a while I have to say light fighters are my most hated ships in this game, and I am SO HAPPY they basically nonexistant on difficulty 4.0 and 5.0.
Sure, they are fast and nimble, as they should be, but the hit detection of pilot cannons are just so bad. It they fly perpendicular to you, even if you aim at the target crosshair and it's dead on, you do not hit because your shots are too slow for them.
- small shot speed increase or a slight light fighter speed decrease would work wonders
Another issue is that on the Dart there is a pretty big window where your pilot cannon shoot in an X past the light fighters even if you are dead on, and the hitbox seems not to be hit at all. - small increase of the light fighter hitbox fixes this
