Contested content provides the purest MMO experience. Allowing players to interact with others within the world created. Players coming together, surviving great tests, and forming bonds is what MMO's should be about. Constantly creating ways to overcome the career griefer within MMO's will only lead us to a game where all of the game is instanced and all players are segregated bar the few rare meeting areas ala Guild Wars. Social skills or the lack thereof should not drive the "innovation" of MMO's. More focus should be put into creating more contested content, more areas within the game where players can experience excitement thus spreading out the population of a game world. More exciting areas would do great wonders to alleviating congestion and griefing. If there are only one or two really "cool" dungeons’ or areas within a game, of course everyone is going to be there.

Guess what pretty much every game is now?
