The problem with the solar grenades is enemies move. Unless you got Atheon into a corner then I guess it could do a lot of damage. Plus Wolf pack rounds pack a punch a 331 Ghorn on a level 30 enemy they do 255 damage each round. And if I recall there are about 6 or 7 of them so that's 1530 or 1785 extra damage on top of the inital explosion. Solar grenades do about 100 something damage and last 5 seconds. Either way I can't see it doing more damage than the wolf pack rounds.
