Multiple issues are causing anti missile turrets to be ineffective in what they do:
- Their rotation speed is too slow, it takes several seconds till they face the missiles and at that point it can be too late.
- They don't lead missiles properly, at large missile speeds the turrets will miss their target by a few meters at most angles.
- They should prioritize missiles and switch targets if a missile is never going to hit you anyway. (but this is more of a feature request so ignore that if you want)
