how does the new account buddy system work?
When they add you do they know your account ID, or some sort of server generated identification code? Or is the nickname listed something that they make up.
also can your old "buddies" convert you to account buddy without asking your permission?
third, is there a way to opt-out completely and only allow people to buddy your character?
As many have suggested, there may be a risk that they might get your account ID somehow, even if it is not disclosed directly. though I have nothing of great value. Also I don't really play enough to make any lasting friends in game, so I don't really care about the buddy system that much.
also how have you responded to the account buddy system - have you been adding lots of buddies or do you have reservations?
