We lost 70% of our player base half a year in

After leaving WoW, some may still be in the honeymoon period. Once that fades, we'll see what happens.

If every WoW refugee leaves this game, it will still be popular enough to make money for Square Enix. There have been, and continue to be, content producers on social media for the game. The Reddit and Twitter communities will still include players who both create and read and remark on the game. There will still be an active FFXIV forum, five years from now, complete with posters who will complain about this-and-that and other posters who will make suggestions to "make the game better so that the entire player community does not abandon the game".

Heck, there are still active players for Lord of the Rings Online now celebrating 15 years of play, even in the face of a final shutdown of the servers in January of next year. Even Old School Runescape is still attracting new players.
