Since I have a life outside of WoW, I don't much care about guild socialization for things like raids, etc. That being said, solo play is pretty much teh same experience you can get out of any number of FPS's or RPG's out there, so what would be the point of playing an MMO solo? Furthermore, I just can't see any challenge in playing solo chars in MMOs any more after having multiboxed. All my future MMO decisions will probably be predicated upon how well they multibox.
