I've seen people talk about how once you hit a high enough level the bronze and silver sections of each daily event becomes a bit of a chore, and despite the importance of completing it there's little "oomph" to get you going through it. I also noted that some people mentioned that even the highest levels were kind of easy once you got enough golds. So I think that, once you complete all 3 to 100% (300% completion hahaaa) then you get to face off a 300% big boss of that daily event's character. Much like 300% Marie? It may not help that much with the complaints of lower level being a slog to get through but I think adding a big incentive to complete all 3 of them may help? Maybe this can be like an enemy that never resets it's status, so you can grind off of them for exp or gold more easily than most of the game idk.
