I made a suggestion before I left the staff a few years ago that we could have small jungle map with a temple inside of it somewhere further up in the world.
If you went into this temple there would be a magic crystal floating on a pedestal and if you walked close to it you'd get teleported into another sort of more fantasy like world/map(s) that would have floating platforms and other more, unnatural things that could make a fun time to explore, but not necessarily walk all over the more down to earth environments and maps spreading out in "Feral Lands". It would be a nice way to implement more funky maps like climbing maps with platforms suspended in thin air, but if the staff ever took that idea into consideration afterwards I do not know.
