@Severix ELO is a system which helps to determine how good players or guilds are. Originated in chess it provides a fair estimtation on how strong a player or a guild is compared to other players or guilds. You can earn ELO points by winning games and you loose them by finishing e.g last. The number of points you can win or loose are determinde by the relative strength of your opponents. This means that you gain little ELO points beating a weaker player but you can gain more if you beat a better player (higher ELO rank).
Because we are planing on implementing guild tournaments we thought it would be a great idea to be able to search for guilds by their ELO rank to see how strong they are.
