Two things to take note:
 * You can change the map difficulty as much as you want, as long as the map is not cleared.
 * The boss gauge would reset every time you change map difficulty. You'll want to switch from Easy -> Normal (no sortie) -> Easy to reset the boss gauge if you want to keep farming.
 * You can no longer change the map difficulty after clearing. Not a problem if you plan to stay at Easy, but players who wants to clear maps at higher difficulties would have to farm the map at lower difficulties to guarantee a S-rank for rare drops.
