I have some desires for when I play the Duviri Experience.
Opt-in for Kullervo fight. Sometimes, a few people or one person can easily solo Kullervo after a certain amount of decrees and it'd be nice if I or other people could still go farm decrees elsewhere.
A sort of "catch-up" mechanic for people who join late so they can almost match the number of decrees the host has. It can help with entering undercroft too early.
Ability to change focus schools when in the selection room
Sometimes, the chest that requires "rhythm" matching locks up. It stays green, doesn't provide a decree, and can't be interacted with further.
Host migrations after completing a stage in the Circuit don't allow players to select a decree for completing said stage.
