My alliance toons in WoW have been in the same guild for the last 6-7 years and we had a rapport like that, which I'd like to think was unusual for a raiding guild that could actually down competitive content :/ In regards to server competition at least. It sounds silly but it's the friendships that kept me playing the game for so long...one or two of them were like how you described. It's possible to truly connect with someone online, and the relationships can be as meaningful as any real-life friendship.

Well what I said wasn't actually what I thought but rather a projection of your own desire to project to me what you wanted me to believe due to your obviously sinister ulterior motives.
