Idea: An airship 'dungeon'

[Enkidoh]

Not just Void Ark either - there are several dungeons already that are actually airships, even if they're not immediately obvious as such. Specifically, the Aetherochemical Research Facility and the Singularity Reactor are both on board the Flagship, the gigantic Allagan airship that serves as the central area of Azys Lla. And speaking of Azys Lla, the Fractal Continuum is also another ancient Allagan airship, this one a warship that the Allag converted into a museum.

And it should go without saying that part of the Binding Coil of Bahamut has you travelling through a Ragnarok-class airship spacecraft. To say nothing of the wreckage of the Agrius serving as the setting for the Keeper of the Lake.

So yeah, there is already airship dungeons in the game, you just have to actually read the Journal descriptions in the Duty Finder and take note of what is actually being said in cutscenes.

Would be fun to have a dungeon or outdoor area like Ru' Aun Garden from XI.

Technically again we already have that too - as I understand it the Sea of Clouds and the Churning Mists were both designed with FFXI's Tu'lia in mind as a reference (one such hint is in the Blue Window area of the Sea of Clouds in the form of the Groundskeeper enemies - in FFXIV these are simply golem type enemies covered in moss, but in FFXI they were 'doll' type enemies, but they still looked similar. So yeah, once again we already have something similar to what you're describing in FFXIV.
