Honest answer: In EQ, it took time to level up. It also took time to get somewhere else. Because of these two things, you got to know the players around you. Whether you were soloing or not, you saw the same people day after day, week after week, month after month. You asked for help for CR's, you asked for ports, you asked for SoW's, you asked for haste, because no one class had all these spells, they created an interdependency among the players. In every modern MMO, you reach max level in less than a week, have no need to talk to anyone, group with random people with a dungeon finder, and never see them again. Modern MMO's have created all kinds of shortcuts in order to expedite the path to the finish line. Everquest was all about enjoying the ride.
