First, this idea is not mine, so credit where it’s due… (rogue I think?)
When ‘clearing’ a dungeon how about we get the option to buy that dungeon as a house? Make that purchase ability one of the perks of the clear. I know I would pay a pretty penny for WGT

The architecture is already in the game in the form of the dungeon, and it’s already instanced, so it shouldn’t be that hard to port out the option to buy it…
