I would really like to see the old dungeons get a quick once over to see where they can make small fixes. They avoid improving old content, so they can focus on making new stuff, and I get that. Though like, I am talking maybe a team of <10 people given a few months to go over the ARR stuff. Do little stuff like make some of the old stuff more fun where there's clear and easy ways to improve it. An example, make it so the three bosses of Copperbell are actually something the party can engage with, and do something about the enemies resetting a bit too aggressively. Similarly, add markers they developed later to old content where they are relevant, like stack markers in Crystal Tower.

You actually can't just keep speeding forward with big decade long persistent projects. Seems like successful MMOs get a renewal at some point, either successfully (WoW) or unsuccessfully (RO). I think FFXIV kind of gets it and I like they are at least touching up the MSQ to be a bit smoother. I hope it means the team got a budget to get a team to tackle this kind of thing.
