I think my happiest moment is to wield Variant Spirit Dart when running as a SCH or any healers tbf. I spammed that dungeon for no particular goal just because it felt ecstatic to have 2nd DoT to throw even when they're uniformly 30s in duration.

Otherwise, I agree with all your points beside Criterion's, which I wouldn't say much as I haven't really dived into that yet. The rewards ain't looking convincing enough though...
