As a former MMO player, I absolutely hated anything that required playing with a group. I mostly played solo (although back in my LotRO days I had an awesome guild to occasionally play with). I remember this being one of the reasons I liked ESO (I haven’t played an MMO in ages so I don’t know if anything changed or my memory of that is bad).

If something required a lot of group play, I was likely to stop playing it and find something else. It really depended on how easily I could ignore the group content.
