Yes, they are a good counter to shotguns, but when they are frequently used to counter everything else (even snipers in some instances) it becomes toxic and broken. Yeah i know they are working on it, but the e fr4 is the only fusion rifle in its caliber most other fusion rifles cant one shot consistently and have no range. E fr4 has kinda a dictatorship on all other fusion rifles, and just like every other special weapon (besides snipers because of actual skill) they allow the user to get a easy kill then pick up special and completely use special for the rest of the match until they die.
