Okay, first off, you spend plenty of time in the light world too, and while most enemies ARE weaker, there are still plenty of times where freezing or extra firepower are handy.
But more importantly… hello, dark pirates? Troopers are a bitch, and the commandos are even worse, what with teleporting all over… sure, they get better with the darkvisor, but either way, they’re a major pain in the ass to kill with the light beam–
But the dark beam gives you a 2 hit KO thanks to freeze+missile effect.
You would want to get rid of THAT?
