The only problem with fusion rifles is the spread. It seems that if using "Aim Down Sights" the projectile spread doesn't actually spread at all. So, you get one-shot-kills at much too far range. They just need to make it more of a cone-shaped, instead of a wide column-shaped one. This would also help it to be a more effective "room clearer" in PvE. Just one dude's opinion, of course.
