At this point will FFXIV collapse if all mods and third party tools disappear?

[TheNight]

The game did quite well before any mods had been developed.
Everyone who plays on a console - and they are a significant chunk of the players - manage just fine without being able to use any mods.

Should all mods somehow cease functioning all at once - which is unlikely in the extreme to ever happen - then I am sure there would be a noticable drop in players, but I am also sure the game would survive handily.

It's not just mods. It's also the community created resources. Who will keep playing the game if all FF14 Discords disappeared suddenly? Almost no one is playing the game because of the game. They are playing it because of what the community has created. Just think of content like Baldesion Arsenal. Almost no one would ever do it if the Discord dies. Or Savage. No one would do it if there are no guides. We owe far more gratitude to the community than to the developers.
