Not sure what you're saying here but this community really likes forced grouping. In general this community prefers MMOs that require grouping at almost all levels. The basic reasoning being: the only reason we enjoy these games is to play with other people and MMOs that allow everyone to solo hamper that.
An interesting take on it was EQ. When I raided the best solo classes were necro, druid, SK and paladin. And the classes least desired in groups/raids in large numbers were generally necro, druid, SK and paladin. Meanwhile raids were stacked with lots of warriors, clerics, rogues and wizards. So this created a dichotomy where the different classes were more strongly typed than just dps/tank/heals.
Though to be fair to my comparison, wizards could quadkite and DPS in raids and sk/paladins were generally awful all around. Actually my memory of this dynamic is really foggy and I should just abandon this post now.
