Heavy Polaron Beams sure do have the range, but they extremely lack DPS. It also irritates me on how much they miss their targets.
According to other people, Heavy Beam Lasers are more useful. Just because of the Higher DPS. Good against rushing Exodus base attacking fleets.
Oh but, the range of does Beam Lasers.... well lets just say, they are easy sniping targets for Broadswords & Venoms.
