Loot. As a raider, it is both boon and bane to us. If you're in a guild that has a system you can agree with, then loot can be a wonderful thing. However, if not, loot can often destroy morale and even take entire raiding guilds under. We've all heard stories of the inevitable blow-up that occurs after the piece someone's been after forever goes to someone who just joined the guild.
That said, as we know we have lots and lots of people with quite a bit of MMOG experience out there, we thought we'd ask you what loot systems you prefer for raiding? Do you still think the oldest is best, and like to run with DKP (Dragon Kill Points), or are you all about the roll and distribute. Perhaps you prefer one of the other systems like Suicide Kings, which goes down a list that moves based on who attends and doesn't loot (thus heading for the top) versus those who attend and loot (who land at the bottom). We're curious what you think is best for keeping raid looting "fair."
