In a recent interview, Yoshi-P talked about wanting to add more into the world to get players out and about with repeatable content.
While I have many ideas and requests like adding lock boxes as drops from FATES, there is a lot they can do to improve them especially when you no longer need XP to level.

A few quick notes:
  • Add a small amount of endgame currency when you no longer need XP, it shouldn't be that much, but a good option while you wait in queue.
  • Update Seals (all types) as a possible drop
  • Add new fates (red?) that are super hard boss versions (basically take some of the diadem and put it in the open world)
  • Add World Fates
