What do you think will happen to a failed data center?

[Oizen]

Pretty much this.

Unless someone is a roleplayer, prepping for 6.3 or going through MSQ for the first time/again on an alt, they're most likely not playing right now and haven't been since 6.2/6.25 launch. I think a lot underestimate how many play strictly for story and then dip out till the next story-related patch launches. Low pop is always a thing, especially if the patches themselves aren't giving enough content to keep all playstyles engaged for months at a time.

A lot of 6.x content has been pretty lacking in terms of longevity.

Ishgard Housing? Gone in a second.
Crystaline Conflict? PVP isn't for everyone, and there are far better PVP games out there for this expierence. Its fine but its gotten kinda stale and the frequent balance issues with it sorta makes it drag.
Island Sanctuary? Boring, Disappointing grind. Get to max level, get the mount you want and drop it. Probably the biggest failure of Endwalker so far, and SE missing the mark entirely. No one even talks about it anymore. Why can you visit each others islands if there's no customization or activities to do as a group?
Variant Dungeons? You do it 12 times if you want the mount, 1 time if you dont, the skills are boring compared to systems we had already for Bozja or Eureka. Neat story telling but you'll finish this content in a week.
Criterion Dungeon? Kinda got sabatoged by its rewards being so lackluster people don't care. I don't actually mind this content, I enjoyed the fights quite a bit, but they're still just 3 mini bosses.
Criterion Savage? Same as before except now its more punishing, not even an extra boss fight or more mechanics, just more punishing because it is.

Everything else is the typical copy paste that we always see, I enjoy grinding out savage tiers, and beast tribes can give a good story, but they're not exciting or new, they're the same formula this game has done for years. Square Enix doesn't take risks and it shows.

Hoping the Deep Dungeon in 6.3 delivers in being interesting content Endwalker, and not just the HoH framework copied and pasted to a T. But I'm not holding my breath.
