I did it. Just grab some other crucible bounties and go play rumble pit. I found a void damage shotgun and just shotgun whored until I got it. It took about an hour and a half. Plus I learned a lot too, from watching other players learning my tactic and countering it. Destiny was designed to have you play every aspect of it, but in your own way. Get a void sniper or fusion rifle if you don't want to go shotgun, and get it done. If they want everyone to have every exotic weapon they would all be buyable. They want you to earn it. BTW thorn sucks balls, just to let you know, you are on the bounty for it. I'd still go for it if I were you, just don't expect anything more than eye candy. It needs fixed, and Bungie will fix it.
