They have always been dumb with nerfs. They nerfed the AK74u in BO despite how dominant ARs still were, they ruined some SMGs in BO2, they ruined the VMP in BO3 etc. They always overdo it. The LMGs definitely needs a nerf but it's not really needed for the Saug, Maddox and Spitfire. Hopefully the Saug is still usable after the patch since it's the gun i enjoy using the most in BO4.
