The Truth About Drop Rates

If you've ever participated in a raid, you've heard countless theories about what rules over loot drops. Perhaps the drops are decided by the class of the first player who enters the instance? Or the raid leader? Well, every time such rumors are posted around the forums, Blizzard denies that there's any system to it, saying that loot drops are completely random. Kylindra of Cenarion Circle server has put together a good write-up on drop rates and explains that "random" drops and fair drops aren't always the same thing.
