When your guild is small, everyone is friends. You know everyone because you play with them and things are kinda normal. As the guild grows, that goes away. People form cliques and you end up with people who just won't even group with other people. And the guild leader is often stuck in the middle of everything. I get to hear everyone complain and mock everyone else. Even when I agree, I know I'm going to have to deal with the personality clashes at some point. It means playing the game with people in the guild is a constant reminder of how much the entire guild is a society. A group of people who enjoy spending their free time playing the same game, and still manage to build walls between them and others.
I don't really care that someone else made you feel bad. I don't care that they did something and now you feel left out. I don't care that someone said something offensive and someone else stopped playing the game and we lost a valuable player. I'm not here to make sure everyone gets along. I have a hard enough time getting people to understand the DKP system, or how signing up for a raid works. I have to make sure people's forum access is set up right. I have to talk to people who applied to join the guild and make sure they are not jerks. I have to check the bank and make sure we didn't have a bunch of stuff stolen. I have to write down policies so people stop asking me questions over and over. Of all the things that the guild needs done, at what point did you think the guild was kindergarten and you needed the teacher to make Billy stop calling Suzy names?
