Everytime I run a Dungeon and see all that "Free realestate" I wonder... Why not add an option to it like: "complete all paths and get available as guild hall"? Honestly, our current guildhalls are huge and dead... Maybe more variety would fix this, and if you look at pretty much any dungeon, you add an arena area (most of them have suitable areas for arenas), add a couple of merchants and BOOM, 8 new guild halls. One other good change would be the possibility of placing the merchants and NPCs where we please, like decorations, I understand some only make sense in one area, but even so moving the NPCs (and nodes for that matter) could be an easy solution to bring more variety to the GHs.
