I'm not too concerned about keeping the teams even. Partly this is because I'm not playing to win (although I'm trying to win), I'm playing to have fun and to learn. The people who have contributed most to the success of the games our team has played have been the people who discuss the goal, agree on a plan, and attempt to stick to it. These are not necessarily the people who have the highest ranking after their names. I think the group dynamic is more important than the individual rankings in determining who does well.
