Having seen Ixion mess, I rather not have a FATE heavy world or worse instanced open world maps...ever
You know it's just a matter of time before people asking instances if it happen.

That said, I do like the story FATEs like in Steppe. It brings the world alive another way.
World lore need to be more rich than just few NPCs, plus the reward is just right
if they put a consumable/currency item like Outfoxed, so they can add new incentive.
Maybe HQ food, all kinds so it's not just one time thing. No more glamors/minions I hope.
