World of Warcraft died because the developers only catered to casuals and world prog

[Ronduwil]

You've either got a strange definition of casual endgame content or you didn't play WoW for years and years as you claim.

I've played it for years and years, and I agree with him.

Dailies and the world quests that replaced them

And back in WotLK, Cataclysm, and even MoP, these quests awarded raid-quality gear. Now they give anima that you can trade for customizations in your personal base that no one else will ever even see. They're pretty much pointless now.

Crafting and gathering

Which you could use to craft raid-quality gear back in the day. Now, if you're willing to invest millions of gold and/or months of grinding, you can craft legendary pieces that can only occupy two slots. Aside from that, you can't even craft nice pets. It's pretty much worthless now. In contrast, I'm consistently crafting HQ 580 gear in this game after working my jobs up. This game doesn't make crafting feel like a complete time/gold sink.

Dungeons (other than Challenge mode in MoP/WoD and Mythic+ since)

Anything below Mythic+ is faceroll easy and awards garbage gear that isn't even on par with what you get from your covenant. Imagine if the only gear you could get out of FFXIV dungeons was inferior to the stuff you buy in Old Sharlayan at level 89, and that's what pre-M+ WoW dungeon gear is like.

Pet battles (sure you could do them before endgame but the reality is we'd all rush to level cap before we'd do them, making them endgame content)

And those award <drumroll> more pets! It's far more cost efficient to buy a Pokemon game. They don't charge you $15 a month to keep playing it.

Solo farms of old raid content for minions/mounts/transmog

Except they broke those this expansion with their stat squish. Players were literally turning their XP off at 50 because you actually got weaker once you advanced to Shadowlands. Blizzard gave the players who enjoyed this form of content a big middle finger.

Whether or not you enjoyed those things, they were all casual endgame content.

But the point is that they're not high quality casual endgame content. FFXIV's endgame content feels much more rewarding. You don't feel like the devs are passively aggressively (or even just aggressively) punishing you for preferring casual content. FFXIV gives you endgame currency just for participating in the MSQ roulette or even the leveling roulette. WoW, on the other hand, doesn't even give you endgame currency for anything less than Mythic+.
