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

[Imoye]

MMO RPGs generally are dying, people want to go back to quality singleplayer games that they can play at their own pace

There's really no evidence to support that claim. Every time a new MMO launches there's massive interest. New World and Lost Ark are the most recent examples. FFXIV is also doing better than ever and has consistently been gaining subs. Other games such as Elder Scrolls, GW2, Black Desert etc. retain solid player numbers. Little is different now from when WoW was dominant in terms of numbers. Back then, a large proportion of the genre's player base was consentrated in that single game, now it's more spread.

Also, people have been saying "MMOs are dying" since forever. The claim holds zero weight.
