* No more duty finder. Dungeons can only be entered from the overworld gateway.

* Time to bring back naked death runs. Wipe and you are not returned to the start of the dungeon, you are returned to your home city, naked and without mounts, gil, or inventory. As in EQ you need to run (or swim, or call for your little branch, or whatever) back to the dungeon entrance, then to the coffers containing everything you own.

* Shared Dungeons. These are not instanced, but overworld caves that any number of parties can contest the mobs, and bosses, inside. If your party is not the lucky one to start the bossfight on the hourly spawn, you can watch the fighting party, then wait for the next spawn.
