How does endgame WoW treat avid soloers?

Messiah, our World of Warcraft site lead, has addressed the soloing question from a variety of angles. This week, he looks at the question from a level 60 perspective:

In most MMO's friendships and communication skills are formed very early on in the game. You grow with other players, you learn to rely on them for help and to help them in return. In WoW, with the game being so easy to solo, that generally does not happen. I have gotten to level 60 and gone into instances with other players, then had to explain to them what an instance was (i.e. what that big shimmering door was!!!). I have had to explain tactics, pulling, tanking, off tanking, aggro management, protecting cloth wearers, and much much more; all to players who are my own level but chose to never group before they ran out of things to do solo.
