The <Riders of Gilead> is a well established guild on the Ysera (US-A) server. They're recruiting for raids on Tuesday and Thursday evenings and use the Shroud point system for awarding loot. You can check out their web site here. This may all seem like fairly standard stuff -- but what sets them apart is their strong sense of coordination and teamwork.
Some time ago, the <Riders of Gilead> helped an old-world PUG work its way through Mount Hyjal. The raid leader was a level 71 holy paladin who seemed to really, really want to tank the content. The Riders were fine with that; it was old-world content, and the whole event was just for fun. But the paladin kept getting more and more belligerent as he repeatedly died. After all, even at level 71, a holy paladin can lack the tools to tank raid content. Finally, after a lot of wipes, the paladin got frustrated and switched away from group loot to master loot.
This wasn't an issue of loot. Hyjal loot isn't very meaningful in the Wrath era; instead, switching the loot to master loot was an insult, like throwing down a gauntlet. When Jinna, the guild leader for <Riders of Gilead>, was unable to reason with the paladin, he asked in TeamSpeak for the guild to get out of combat.
Amazingly, the entire group did so. Jinna negotiated the loot back to group loot and ended up leading the remainder of the raid. He did not kick the paladin who'd started the fight, and the PUG went on to complete the instance. Moments like these are what binds a guild together and shows why leadership is so important to a successful group. It's more than just loot; it's shared teamwork and vision.
