Honestly FATEs are fine, but this holiday event did them in such a way it was
unenjoyable. They had no connection whatsoever (aside from egg drops) and
their respawn was bad.
As for the coddled spriggans, maybe had they been in more random places, or
if they roamed the entire map, it may have been a bit more pretty. But they were
camped and had long respawns.
I do like the use of chaptered events, it makes them feel longer or as if there
is more to them. My only gripe with this one, was that each time it was the same
thing, with a negligible increase in difficulty, with not much story added each time.
