I think a big reason for this I don't usually see people bring up is the fact MMOs are so grindy. When you're doing the same dungeon over and over, dozens of times a day, several days a week, you're going to start to tune out.
If MMOs made dungeons more of a big investment, like harder fights, longer runs but with a higher chance of rewards so you didnt have to run them as much, people wouldnt go zombie mode
