Congrats on finding out!
Weird take. I'm mostly content (a few complaints aside) because I play other games / have other hobbies and am not completely codependent with FFXIV.
Um chile anyway so...
I can't speak for everyone but the reason I don't mind the "content slop" is specifically BECAUSE I have other games to play. I was hella addicted to FFXI for a number of years where I barely played any other games so I know how it is. 14 for me, is a much more casual and easy game that works just fine if you only play when major patches release.
That being said, I would totally play more often if they released content quicker.
It's actually kind of ironic.
One of the community's primary grievances is that we want more reasons to log in for dedicated players.
Of all MMOs I'd say FF14 players are the most comfortable playing other games because you can jump in and out whenever you feel like. Gearing is super easy, and the content that is added never goes anywhere. (Except old Diadem but I think revamps don't count)
Wanting worth for your sub payment isn't an unreasonable ask with the wait times for new content. If they made demolition timers go away permanently, watch how the sub numbers would drop. But they know this, so they dont do it. Dropping the demo timer to 4-6 months would be enough
