Overall, Duality is one of the better Exotic Shotguns, but The Fourth Horseman is better. There could also be times when other Shotguns would be preferable.

Is duality good in PvP Destiny 2?

In PvP Duality can be a fairly flexible shotgun. It can be used for close range scenarios, but can also have some solid range with the slug shot. It is still outranged by the Chaperone, however. PvE is where Duality truly shines.

Did duality get buffed?

However, Duality is getting some major buffs, which should make it extremely useful in both PvP and PvE. For the PvP portion, the damage falloff distance will be increased by 1.25 metres, meaning it will become one of the longest range shotguns in the game.
