The idea would work if housing was more common. As it stands now, only a handful of people out of a ton have houses and if you are one of the many who don't have one, getting a piece of furniture as a reward in a dungeon is a slap in the face "Hey, see this niiiiice chair? If only you had a house to use it in!" That's why a lot of people hated that one seasonal event that offered nothing but furniture because if they didn't have a house, then there was no point in getting the items.


Not to mention that you couldn't really sell the furniture drops for a good chunk of change unless the drop rate was pre Atma numbers.
