From Destinypedia, the Destiny wiki
This weapon's Year One roll is seen as a very good weapon both in PvP and PvE thanks to the explosive rounds, which deals massive area damage. It is excellent for clearing out swarms of lower-level units such as Dregs or Goblins. The Year Two variant can roll with most perks, allowing for more specialized PvE and PvP guns.
