Bad juju is loads of fun, looks great, has a cool sound! Unfortunately at the moment it isn't good for crucible because it frankly sucks, but in PVE you can totally have fun using it's unlimited clip to wipe out crowds of dregs, acolytes, thralls or other enemies that go down in 3-4 critical pulse rifle bursts. Just make sure to carry a good special for bigger enemies. When it gets buffed if ever it will be something really special!
