WoW didn't really take those. Let's not forget, OG WoW is pretty much just a better version of EverQuest.
Most people agree that WoW's "downfall" starts somewhere around the end of WotLK and many consider that period of time its greatest. And what happened right around the time WotLK starts to wind down/end? It just so happens to roughly coincide with the rise of Facebook and mass adoption of smart phones. These aren't really coincidences. And as people start to look elsewhere for their social interactions, Blizzard and other devs started designing their MMOs accordingly. That's also roughly when you start seeing the rise in popularity of cross-server solo dungeon queues, PvP arenas, etc. too.
Almost as if players no longer really cared about that aspect of MMOs anymore and devs in the industry start designing around it accordingly. And the pace of all these systems only increases as attention spans start to dwindle, social media gets even MORE popular, the advent/rise of Discord, people wanting shorter and shorter bursts of content, etc.
Face it - the thing that made MMOs the MOST novel, doesn't exist anymore. That genie is out of the bottle and can never go back.
A lot of the boomers on here that bemoan about "interdependence", "name mattering", meaningful consequences, blah blah blah? It almost perfectly describes Albion Online. Yet almost nobody plays it. Almost as if nostalgia is the only reason people think they actually want that shit in their MMOs in 2024.
