What level are you? I waited to do the bounty until today. Mostly because I now have atheons epilogue (void AR), void shotty and corrective measure (void heavy) on a voidwalker. My super, melee and nade are all void as well so every single kill I get is void. After just 5 matched of control I have 246 points. Maybe hold off until you have the right guns to make this daunting task a little easier on yourself.
