SMGs absolutely need nerfed, they absolutely should have alot more recoil then they do, plus their damaged at distance is a joke. They can easy beat out assault rifles and LMGs for accuracy. They are way too accurate at distance, they have no bloom and are just laser. In reality SMGs suck past 75 yards especially when you are going full auto. This isn't star wars laser beams.
LMG and assault rifles should not be losing to a SMG up close if you fire the first rounds, much less at distance. 9mm pistol round to a 556 and 7.62x51 rifle rounds for example have substantial more energy, come on dice. If SMGs worked as they should it would force players to change up their kits based on the maps they play vs SMGs all day owning everything else no matter what. IDK who they got their weapon info but never listen to them again. Also longer barrels makes your accuracy worse in the game accord to who I would like to know, who told you all that nonsense.
