It specifically says to defeat any target using solar ignitions. But I've seen 3 problems with this: Ignitions from a caster Ergo Sum with Perfect Fifth aren't counting. Caliban ignitions aren't counting And even Gunpowder Gamble isn't counting. Whatever I did it with already in strikes, I've been stuck at 50% for almost an hour. So either not all ignitions actually count as ignitions, or it's a bugged node because there's no way I'm not getting these kills. So, you replace bounties with a reward system that forces you into modes you don't want to play or use weapons/ subclasses you don't want to use, and not all of those nodes even progress right anyway.
