The EM2 never got nerfed in the most recent Warzone Season 6 update! Even J-God himself said so!
This was on my radar as the best gun in season 5 that was sure to get nerfed in the update. Even in the patch notes it lists the gun as getting more recoil, but it's completely non-existent. On top of the no recoil, it's one of the strongest, if not the strongest gun in the game power wise. You gotta give it a go and I'm sure you'll like this loadout.
