As i have said before, Juju is a crowd control weapon. It is meant to quickly deal with hordes of trash mobs, enemies that are unshielded. Bear in mind that these types of enemies appear the most, be it in strikes or raids. So, for a weapon that can quickly burn them down without having to pause to reload, it has its uses. As for the tougher enemies, i am nothing if not prepared *pats Purifier and SWARM* Btw i have used it in crucible before. It's actually quite fun if you know how to aim.
