A lot of this comes down to the current design of the game and many QoL features.

Like, you can actually QoL the soul out of a game and community building.

One such example is.. Everyone likes the crafting change from Endwalker where they delayed savage so people could craft - Which is nice for people, but it does also actually take out the networking part of a game, because you wouldn't need to network with people to get the gear. Because why would you when you can either do everything yourself, or get it far, far cheaper from a market without the need to connect to get things on premium.

Same thing with queues.... Why would I go to a part of the open world to queue for something when I have this glorious thing called a duty finder to queue from absolutely anywhere, including Limsa. This is something people don't understand about the 'Limsa AFKers' -- Many of them actually have no reason to leave a city state because the game rarely requires or even asks for it.
