It is the point I have made on this thread
The majority of mmorpg players don’t care about social stuff, solo ques are extremely successful and liked in all the mmorpgs they have been added because people just don’t want to bother with the whole social process of forced group content.
It’s why arenas are so dead and aren’t touched by the vast majority of the player base. Same happens in rated bgs.
Meanwhile games that have a solo que show a far bigger participation in most activities cuz there’s no talking or grouping up with other ppl, just quint and smashing players
