First off, following release I played Nightingale and nothing else for three weeks! Got quickly to 86 hours and then stopped. There's nothing new to do! There's no reason to keep playing. The end-game grind gets boring fast. Every realm is easy at that point. No more challenge. I'm not interested in building a vast fancy estate because no one will come and look at it.
So please, forget timed festival grind-fests, give the players more end-game meaningful story (non-grind) difficult content such as new quests, new realms etc and make it hard.
Plus, more outfits, of course.
Thanks for an otherwise excellent game.
