The League of Laws is an inter-clan council.

It is currently advisable to discuss the clan rating system. While the project for players is acceptable until the end of the year—at her request, I have already calculated everything for all versions—it remains unclear how to handle clans.
The rating system itself can be viewed in the topic of 3 tournaments!

Yes, this is interesting and necessary to discuss. Just in case, a well-known system could be used where each clan puts forward 3 players per game for sparring matches. In that case, with a score of 3:0, clans receive 10 and 0 points respectively; with a score of 2:1—6 and 3 points. If a draw is recorded in any of the three duels, the participants bring 1 point each to the general tally. Later, game results can be recalculated using new rating systems.
By the way, why not move your system from the Heroes 3 tournaments topic to the General ratings topic, if it applies to all parts? :)
