4) You do not have a class that is level 90. This means that you don't have experience in endgame raiding or activities that other people do. You have nine years of mostly single-player, "solved" content to do by yourself to keep yourself occupied. Plenty to do. Once you finish it, then what? Perhaps a "break" to "play other games"
like Yoshida suggests? Many of us have already taken a break. We pay monthly in the hopes that someday we can have something to do in our favorite video game, which is this one.
A single-player game is fun for your first play-through, but after you finish it, then it's over. Why are we required to pay monthly for this? We were lured to FFXIV in the hopes that it would be an online game similar to WoW, Fortnite, Minecraft, Apex, GW2, PSO2, OSRS, etc. that has a persistent online community. That's what it was from 2013-2022 before the big single-player shift. You don't know what that's like. Now we've lost our favorite game and many of us are still in shock and bewilderment that it could fall apart so quickly.
It takes a lot for us to piece our (personal) lives back together again. Eventually we will, and we'll leave this place so you can have the game all to yourself. While you idle and play other games, of course.
