actually only the bolt grenades and skip grenade are auto targeting genrades, the rest are not. Skip grenade tends to target only one person while the warlocks have auto targeting grenades on every subclass. Dying is dying, doesnt matter if you happen to die in a nice place. burning out over that long forces you out of the fight for the burn duration and the revive time. DoT of even a little bit like with the incendiary grenade is pretty strong as it is but how long the burn lasts on sunsingers is just insane. Go to guardian GG and look at the win and k/d stats of ToO and sunsinger. Players using VF, ToF, with firebolt grenades are hovering around the 60% win rate while none of the other classes really have skills that hit the 60% win rate aside from hunter control jumps and a few bladedancer perks. Better yet, sunsingers wearing light beyond nemesis sit at 57% win rate which is much higher than the other classes wearing fast res gear where the others sit around the 50-55% win rate.
