Cerberus+1 is a body shot weapon. Rarely does it ever hit headshots to secure a kill, and with checkmate being all about headshots, this weapon suffers even more than it already did before checkmate. I've also noticed that cerberus total damage output has been nerfed in season 17 and STILL has yet to be reverted. There was no patch note about this, and even after a former bungie employee said they would look into this on Twitter, it is still a problem.
