I would like to offer a concept for consideration to balance team/country play. Don't know if anyone remembers the (ABA) merged with NBA mid-seventies) each year the team with the best record would play the allstars from the rest of the league.
My concept would be to place the squads that finish:
1, 4, 5, 10, 15, 16, 18, 22, 25 as "Bishops"
2, 9, 11, 12, 17, 19, 20, 24 as "Knights"
3, 6, 7, 8, 13, 14, 18, 21, 23, as "Rooks"
I would be interested in reading other methods to balance the number of players per side. Another option is that of a CS server "auto team balancing" but then you would have squads going after each other....that would be fun also.
