It seems that Breach Loaded Grenade Launchers with proximity grenades are doing less damage than intended on PvP. This nerf to its damage has been noticeable for a few weeks now with it doing 149 full damage and not 180 full damage from non-sunset grenade launchers. Heavy Grenade Launchers do not seem to be affected with this nerf glitch. I looked it into known glitches and noting came up about this. Hopefully this glitch will be resolved quickly.
