Honestly, I think the Moon is perfect. It has exactly the atmosphere you'd expect on a moon. It's "quiet", desolate, and barren. I mean, it shouldn't feel like the surface of a planet, it's the moon.

That being said, I would love for a bit more interaction there. Another dungeon, besides the 2/3 we have now. A deep dungeon, maybe even a variant dungeon. I doubt a raid would be on there, but, I'd like to still interact with the Moon, even post Endwalker. Maybe another reconstruction effort?
