If you're doing that melee 5 cursed thrall (super freaking hard) if you're a hunter i recommend triple jump, everyone else i know brings a titan for support with blessing. Easiest place i got it was patrol on lunar complex when you kill the servant of crota (sleeping/injured thrall) when he spawns the cursed thrall u gotta stay in that corner n lure them 1 by 1. I know some people did it on i believe the summoning pits while u wait for the door to open, second wave i thnk is cursed thrall but u gotta make sure u let the other players know not to kill the cursed thrall, take ur time. Get two to three then back out to orbit and run it again to avoid death
