Personally, I would really like an area with lots of tunnels, deep uncharted levels and perhaps even monsters tough enough to fit in a dungeon of their own. However it is not a dungeon because it's a normal zone like Yanxia, Western Thanalan or the Sea of Clouds.

Up until now the only zone types have been the open world ones -- so it does feel like there is room for the closed type of zones too, right?
Anyone else that's misses some temples, tunnels, mines, tombs or ancient crypts to explore? Want to (not) get lost trying to find our way down there?
Did you turn left, right, right and then up? If you did, then why are you facing a dead end right now instead of the great hall you were looking for? Time to backtrack and... Ok, that was a trap door and now you better have that Sprint button off the cooldown because those undead look hungry! :3

So, what do you guys think?
Am I alone on this one?
