I use it all the time, it's the best exotic primary in the game, with 3 exotic perks, saying it's useful for only arc burn is silly, in coe adds another 50 to any kill because you basically damage every enemy to get assists, it reloads itself on double kills, done easily with the exotic effect, AND charges your super quickly, AND the only elemental primary... Soooooo, that's all pretty good to me, and I'm not a fan of auto rifles
