Bringing Back Hamlet Defense?
Maybe this has been brought up before, but it would be a pleasant surprise to see Hamlet Defense come back to FFXIV. It was one of the few positive end game options that came out of 1.0.
Essentially Hamlet Defense was a tower defense instance against a beastmen invasion. Where you and your party would try and stop the beastmen with the aid of various NPCs before the beastmen destroy the instance's cache supplies.
There was also a preparation time for gatherer/crafters to aid in the defense before the instances themselves. It was neat to know of but I didn't participate in that aspect myself so I can't say much about it.
Big reason I'd advocate for it's return is 2 reasons:
1. It's a nice alternative from the 2.0+ DDR battles with a single boss in a giant circle we see in every update.
2. It gives beastmen some sort of threatening appearance in this game again. Something this game has always struggled with, at least in my opinion.
