Raid guild loot systems other than DKP?

[Lhancelot]

I am just curious what loot systems are in effect besides DKP?

I have heard about <Clue> using /ran on ALL loots, is this true?

Are there other guilds that also use this method? How far have <Clue> and other guilds who use this system for loot progressed with content?

What other systems of loot is there besides doing /ran and DKP?

Just curious if any other guilds have found ways to make it fair for all members to get loot equally, or if all raid guilds pretty much have a core group of pixel fiending greedy nerds that drive their guild like slavemasters driving their zerg to gobble up as much pixels as possible for their own greedy ends?
