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

EverQuest did have some toxicity - like people who would train camps to kill everyone as in EverQuest all of your items would remain on your corpse and you could lose hours and hours of XP. People sometimes also fought / KS'd exceptionally rare spawns - things that could take hours or even a week to spawn.

EQ was special back in the day though as more often than not it was cooperative and your reputation in a small community where you can do very little solo mattered. That said, I was a teenager when I played that so I'd never go back to that design philosphy given how time consuming everything was.

That was more random rogue players being toxic though. Guilds and raids usually didn’t have that atmosphere.
