Bad Juju and VM aren't really viable options. Juju doesn't have the bang it should, and without an elemental modifier, it's probably not a good choice in high level end game content. VM just doesn't have enough ammo to take out waves of bullet sponges. Dude is right; once again, Jellyhorn will be a deciding factor in fireteam creation. I would never tell someone "no" because they don't have it, but the recruitment section certainly won't hesitate.
