The Daily Grind: What things should MMOs explain to new players?

Games do not like to explain the concept of roles to players. This is not to say that they don't expect players to take those roles, most frequently the standard trinity setup; rather, those roles are never explained in depth. There's no tutorial in Star Wars: The Old Republic explaining what a tank is or how you will want to play one. In a game like Guild Wars 2, which has a radically different role structure from every other game, you'd expect more explanation, but it offers even less.

This is a smaller part of a larger problem: Many MMOs are built with the assumption that the players are familiar with certain core conventions. So you get tutorials on movement but not on roles or character builds or group behavior or anything that you might need if you've never played an MMO before in your life. What do you think MMOs in general should explain to new players? What areas are lacking in resources for anyone getting into a game cold?
