So there are thousands, hundreds of thousands of chest?, tbh I've no idea how
many are in the game. All good things come to an end and these also need an
expiration date. Why not randomize it and have an event where a random chests
will come alive and wander into Arelium/Shadowkeep/etc. Mimic difficulty could
be mostly slot dependant--or not and whomever kills the Mimic will find that
all the loot taken will have their name on it. This will provide
participation for all levels of players, dest some of the mass number of
player chests out there that contribute to stagnation in sales, commerce for
merchants/alchs etc.
