I actually used atheons epilogue for a vast majority of the kills and it only took 4 hours from bounty pick up to completion. This is one of the few weapons you really have to work hard to get. Edit: thank you to everyone in allowing me a small victory, and ignoring my lack of crucible play time. I appreciate it guys and girls! Edit 2: to everyone that is currently doing the bounty for the first time, or 3rd time. Keep pushing and you can do it! Good luck guardians, greatness awaits you!
