I don't think anyone was trying to make that correlation. They were merely saying that while skill is important, even a Sun Tzu wouldn't be worth keeping around if he makes the rest of his guild feel like crap.

Of course not! I never indicated that I'd do something like that. There's no point punishing 38 people for the wrongs done by one person. What I was saying is that a guild that has players that are constantly and consistently rude and insulting is not a guild that's going to last, no matter how much of a purplez machine it is. But the point is that the attitudes of the other raiders do make an impact. In the words of my good buddy John Donne (:P)
"No man is an island, entire of itself
every man is a piece of the continent, a part of the main"
Maybe it's a faux pas to quote poetry in a raid discussion thread; I don't know. But saying that you shouldn't be affected by the attitudes of other people around you is a bit unreasonable. We're all only human. It's an MMORPG, which kind of reinforces the whole "You are not independent from other people" theme. Everyone has their pride, and nobody likes to be insulted. Yes, there will be some flipping out (I did just tonight at a priest who was rezzing non-rezzers before rezzers :P) but it shouldn't be, as a general rule, done by the rank and file of the guild; that's what the raid leaders/officers are there for.
