Its not so much that it destroyed the social aspect because it didnt of course, its simply that it was yet another mechanic which reduces, not increases, social activity which is surely the entire point of an MMO, otherwise might as well play offline. The original pre 2000 MMOs understood that but over the years the socialising got more and more watered down until you were lucky to get 1 word from people. Which is a pity, especially given that the entire multiplayer RPG genre is the offspring of pen and paper RPGs which were enormously social things. Pity really that so many MMOers lack the desire to actually communicate with other people. I'm still in contact with people I met in MMOs 25 years ago, we've flown around the world to several countries to all meet up. Been great...but something the "heya....cya" brigade miss out on.
