A Realm Reborn dungeons weren't perfect. Some had some neat gimmicks, like using Magitek Armor in Praetorium, but then you also had Toto-Rak or Dzemael Darkhold.

I wouldn't mind gimmicks coming back to dungeons, just so long as they aren't pace-breaking and are fun to interact with. Not "the goop on the floor artificially extends the length of the dungeon".
