Well the void kills part (which I assume you're referring to) requires you to keep a pretty low kd. I got it done in 3 hours of crucible with a NLB, Void matador (no rangefinder or shot package) and void BTRD. It really isn't that hard. I was even a hunter so all my kills were from heavy and low range shotgun. And the Xyor strike is really easy as well. Bad Juju required you to grind 25 strikes which took forever, about the same amount of time as the void kills if not more. Yet it isn't OP and 2 shots.
