Nothing seems to cause more drama in a guild or raid than loot distribution. It never seems to matter how or why someone got a piece of gear from a raid boss, someone else is always upset.
That is why, over time, many different systems have evolved in MMO’s, including World of Warcraft, to help deal with this issue. In general, each one aims to make loot distribution more fair, even, and transparent. But are these systems even working and relevant in the newest expansion for World of Warcraft? How do they stack up in post-Cataclysm Azeroth, and which one is best?
