in Danger Missions is commonplace, because they're so difficult.
So! Speculation about the next Danger Mission down the line, anyone? I'm thinking the next one will be related to Beasts or Gremlins, since those monster families haven't had the focus of a Danger Mission yet. Or maybe a specific status effect will get the limelight?
Beasts are broken at the moment, but appear in HoI. Gremlins have Festive Hell-Mountain.
I'd rather there be more boss stratums with shadow lairs as opposed to having yet another cycling mission. What's wrong with permanence?
