I main both sunsinger and voidwalker. 2 very different subclasses but i love them. Sunsinger: main use for PvE and 6v6 pvp. Solar grenade with viking funeral. Sometimes i use angle of light for fun. Flame shield and radiant skin. Almost never self rez, definetly not in crucible. I always focus on agility/recovery no matter what subclass i use, and discipline is my main stat for Sunsinger. Voidwalker: my main for 3v3 pvp. Also for funsies in PvE with obsidian mind, damn man, if you hit enough enemies with your first nova, your second is already charged. I use blink, vortex, bloom, scatter nade and life steal. Scatter grenade in combo with nothing manacles. Nova bomb is so strong in 3v3 because it shuts down every other super in the game. It can definetly save a game or a killstreak for u.
