Problem is: -They connected projectile speed to the range stat on fusion rifles. -They don't land crits and their spread is terrible so if a single bolt misses, you're essentially toast. -They're harder to use and don't net you any advantage unless you're in the most niche situation. -Bungie keeps nerfing them. Even when no one is using them. I was using a fusion rifle today and got a few good kills. Unfortunately, the gun with good range and stability couldn't kill a guy at 15-20 feet. Note: This is the FWC variant of the Thesan. So it has good range and almost max impact meaning it requires only 4 bolts for a kill. Despite a 2/3 full stability bar and me adjusting for recoil. The gun is about as consistent as an ugly hooker. I ended up using it like a shotgun hip firing point blank at people just for kicks.
