Yeah, but I don't see people sit around pretending that Live is one big happy MLP:FIM-Carebear cross-over where everyone makes friends for life with everyone they manually group up with.
As for Guilds and friends: Those are also things Classic zealots like to pretend are no longer part of the game for a fact as they lament the days "when this game had a community feel!", so I'd say it's entirely appropriate to bring those up.
