User blog comment:Derp2000/Is the Bad JuJu worth it?/@comment-25876510-20150225070129

Bad Juju is one of those weapons where you have to put time into it in order to get the most benefits out of it. It does suck, on having to use it quite a bit to upgrade, but the String of Curses perk would work amazing: Imagine you're facing 1000 Thralls (You know, the Abyss). You could technically just stand in one place and mow them down constantly. And don't forget that it's Full Auto.

Also, most Primary Exotic weapons do NOT deal elemental damage. Exotic Weapons like the popular SUROS Regime and Thorn don't have elemental damage. The only Primary Exotic Weapons that do have elemental damage are Vex Mythoclast (AKA the Bane of Existence in Crucible) and Nechrochasm.

Or you may not be one who likes Pulse Rifles. And honestly, Red Death's purpose to us seems to be simply for Hard Crota and health regen, which the SUROS is also capable of.
