Rotation time sucks. Almost no incentive to play daily
Quests are now grindy as hell, rocket racing style. It turned into a chore, most of the time a boring chore.
Directly related to 1 and 2, players leaving all the time now. More than ever.
You cant get new quests while you are in the score screen after finishing a song, so you have to leave to get new quests.
If you care about efficiency, then you'll complete everything you can in a song then leave midway and start a new lobby. Combine this with "do X things in a party" style quests, or having "Play X instrument" twice in your quest list.
Now that quests give you main battle pass xp, people just come to festival to afk farm quests like "Play x instrument Y times" or "Get X band stars while playing on a party"
Or maybe you just dont want to play the same free song for the 50th time
