OP probably hasn't even completed all the casual content the game has available right now.
If so, I'd like to see their Ozma mount, all available relics from all expansions, all completed versions of the Elemental Eurekan armor, every single piece of the Bozjan sets upgraded, every triple triad card, maxed Trusts in every xpac, all deep dungeon mounts (can be done with team, don't need to do solo), every BLU spell and every challenge from Masked Carnival completed, every mount and gear set from Island Sanctuary, every rare animal from Island Sanctuary, all crafter/gatherers with at least 100K points in Ishgard Restoration, and I could keep going.
OP is asking for content they're probably never gonna finish, while not having finished a ton of stuff that's currently available. Either that, or I'll be damned if they can provide all the things I mentioned above.
What is it that you want then? A padded MSQ with a segment where you have to go kill 1000 A Hunt Marks to continue the story? An Alliance Raid that allows you to run it only once every month? Hildy quests being time gated to only one every week?? Do you people want all those BS retention mechanics shoved into XIV? Do you seriously think OP would even bother to complete any of those tasks??
This thread is insane.
