It is true that you can please some of the people all of the time, and all of the people some of the time. but not all of the people all of the time. Guilds will always have some kind of problems. But most of these can be prevented by carful recruiting. Be honest with your recruits, tell them what your goals are, loot rules, back flagging. Then stick to them. Everybody wants the uber item. If they have an understand that you can do this target/evet several times, then people are more inclined to wait there turn. If all of a sudden you stop, for whatever reason, you're bound to p**s somone off. but they would be more inclined to understand if is was communicated well before hand.
Basicly guilds cause thir own problems. If you have whiners, b******g, or arguments it's because the leadership has failed in some way. By not recuiting compatable people, not keep members informed, or sharing the in the decision the direction the guild is going to take. When leadership breaks guild rules, bends them to fit their own needs, or simply won't share the responsibilities with others you will always have problems.
The statement is true, but preventable....
