actually the vex needs to be returned to it's original state in PVE because right now it's not really worth an exotic slot. it's only good against lower tier enemies and that's only if you get headshots the second you come up against a major it turns into a water pistol. Oh and by the way did you know that a 331atk vestian dynasty out damages a 365 mythoclast if that doesn't tell you the mythoclast needs a PVE buff then I don't know what will.
