Dragon Kill Points

Dragon kill points or DKP are a semi-formal score-keeping system (loot system) used by guilds in massively multiplayer online games (MMO). Players in these games are faced with large scale challenges, or raids, which may only be surmounted through the concerted effort of dozens of players at a time. https://en.wikipedia.org/wiki/Dragon_kill_points

2. DKP rewards attendance
3. Random Roll rewards mediocrity

So it should come as no surprise that almost all top guilds use Loot Council.... If you want to go down the rabbit hole on loot systems just search for "loot system tradeoffs" and click around. Lots of passionate discussions to read from decades of raiding
