Hi there,
I would like to suggest an idea to give more incensitive to people to join a clan. The idea is to simply add a ladder for clans.
To be featured in the ladder, a clan must have games played by at least X different people: the rating system would be a standard point system based on the MMR of the opponent. To prevent one person-clan, one could imagine that the points a player would bring back to his clan will have a diminushing return with respect to the number of games to incentivise clans to recruit and have several people queeing instead of 2-3 hardcore players.
If you like the idea or have suggestions, please react to give more exposure to this post and have the devs read it.
