What the heck are they good for aside from killing two thrall at a time if they are swarming? They seem like a weak crappy shotgun with a delay before it fires. A fatebringer does it better anyway. I never use these worthless weapons anymore, shit jumps around so fast it's hard to hit until you figure out the timing but even when you do they take a couple shots to kill anything large. They might have more range than a shotgun but they spread the shots too far and suck at mid to long range. Many weapons are better for every situation I've found so far. Might be worth the hassle of the delayed firing if they were one shot kills on majors and ultras but so far I've found zero advantage and much disadvantage. Where if anywhere do you guys use fusion rifles?
