back in the old days of mist and automatic leveling of equipment i used to prefer getting graveyard over treasure vault because it was more fun and generally gave better payout
now that treasure boxes drop rarities which fuel the constant desire to get more stuff leveled up treasure vault is now much preferable, it was a change for the better for the treasure vault, but graveyard is just another depth, generally with less treasure boxes available but heaps of easy monsters, its almost a bore
it needs an update to buff the challenge it should provide
