There is something about high end, hardcore, raiding guilds. Something that instills a sense of political maneuvering in it's members. When ex-hardcore raiders join my "casual" guild, they rarely voice their opinions in the open. They find the group of technically proficient players and join that group. They begin complaining about mistakes and poor decisions of others. They don't point out errors or problems publicly in the forums. It's all hush-hush, and "I don't want to rock the boat."
Like we can't take it. We'll be offended. That someone else is a good player with good ideas. Instead of "Hey man, try doing X and see if your DPS goes up.", we get snickers behind people's backs.
