Talk:Elo rating system/@comment-4300178-20110815202356

I'm surprised that LoL's ELO system was modeled after a 1:1 chess system. Multiplayer ranking isn't exactly a new concept, and LoL dropped the ball on this one:

"In particular, the ELO ranking system has been used successfully by a variety of leagues organised around two-player games, such as world football league, the US Chess Federation or the World Chess Federation, and a variety of others. In video games many of these leagues have game modes with more than two players per match. ***** ELO is not designed to work under these circumstances. ****** In fact, no popular skill-based ranking system is available to support these games. Many one-off ranking systems have been built and are in use for these games, but none of them is general enough to be applied to such a great variety of games."

IMO: A good measure of LoL ELO would be: KDA + towers with perhaps weighted averages depending on the class of the character (tank/assassin/support/etc). Minions should have no effect because farming doesn't exactly mean much in terms of your overall contribution to the game.
