Primary: Atheon's Epilogue or Word of Crota (if you have access to it). Choosing between those two will be based upon whether you prefer hand cannons or high RoF, low impact auto rifles. Secondary: Praedyth's Revenge or void fusion rifle of a popular model (I don't use fusion rifles in crucible outside of the Vex- they don't do to others what they do to me haha). Heavy: Corrective Measure or Truth Corrective Measure will let you string together a longer kill chain, but every Truth rocket you shoot is pretty much going to be a kill. This bounty seems like a beat, but just stock up on crucible bounties every day and stop playing crucible when you get that day's bounties done so you don't lose your damn mind!
