umm.. that's exactly what I do in the video lol Embrace the Void / Hunger / Nothing Manacles with a sunsinger using Song of Flame / Praxic Fire. You throw out grenades faster than sunsingers this way. I nicknamed it because it was such a surprising change in playstyle, that it didnt feel like a voidwalker. it felt like a sunsinger with homing grenades, with nova bombs, and a Surge boost to speed to make everything even faster plus, Song of Flame can be used on your whole team, imagine how many nades would come out in a raid o.O
