My vex only comes out during vanguard and crucible bounties, such as rapid fusion rifle kills for vanguard and fusion rifle sprees for crucible...absolutely useless in any other instance.. Uses too much ammo too fast and holds not nearly enough in reserve..even with solar burn on, its garbage. Ive had it for about 8 weeks, fully upgraded it the first week and hated it by the second. Beast loadout pve badger ccl, black hammer and Ghallahorn. Pvp up for anything/shadow price or SUROS, 77 wizard, unfriendly giant..i barely use my SUROS either.
