CoD (and competitive multiplayer online games in general) did not even exist during these times. It has nothing to do with the playerbase at all.
Look, I think the main reason PvP is so polarizing in MMOs is because none of the skills you learned in PvE carry over. Healers don't have to run for their lives every second of a dungeon. Black Mages never thought they'd be using sleep so much. The enemies you attack run into the tank's face and you kill them, they don't sprint in circles and run behind walls and CC you for 20 seconds at a time before one-shotting you.
It's just too contrasting of an experience. So in that sense, until SE finds a way to actually incentivize PvE players to queue for the content it offers, i dont think it'll be popular. They'd have to add a mode where you do more than simply kill players.
