Invective is the only shotty I use in pve/pvp. I just got the secret handshake from an engram a while back and noticed how its rate of fire is absolutely terrible, and does hardly any damage to same level or higher enemies. You'd think with a slow fire rate one of the other stats would be buffed to balance the weapon, but that is hard to come buy with dlc shotguns. I really miss the comedian and the invisible hand m7, best shotguns in the game still.
