MMO means you play the same game in a huge shared world together with other players, yes, even outside of actual group content. Otherwise 4/8/24 players parties shouldn't be considered as "Massive" as in the first M of MMORPG, even though old-as-dust classic MMOs like EQ and what they are called love the group/raid-or-die mentality. And furthermore, more Trust content or not, people who enjoy playing with others, will continue to do so in whatever form and shape they wish (FC, Linkshells, statics, *other means to be inserted here*).
