First and foremost, I'd prefer if they could raise the quality of their net-code to, at the bare minimum, a passable standard for the modern day. I consider a passable modern-day standard as something comparable to live-service dependent games released since 1/1/2020, or something similar in quality to Steamworks SDK's networking API's developed by Valve and provided to devs as a solid groundwork for building their own multiplayer net-code. Or really any production-ready API developed since 1/1/2020. I feel like that's not an excessive mark to hold an MMO to.

Obviously this would be expensive, take a lot of time, and require some hardware adjustments - to say the absolute least. But it's not like they literally haven't had the opportunity to do this while they were treading neck-deep in pure cash. Instead, the money got pissed away for some of the worst gaming flops in the company's history.

If you want to experience an "offline mode" then go to Dynamis and have a blast. That DC is so dead that you basically have Limsa to yourself on some worlds
