With the challenge to try to divide a group of people into fair
teams, while simple dividing a group of people into equal (or as close to equal)-sized sub-groupings is the simplest way, it may not always result in an even distribution of skilled players. Moreover, it is often difficult to determine the relative skill of one player to another.
That said, if you have some sense of some of the players, but not for everyone, when setting up teams, do you think it is better to try to divide the known skilled players into more balanced opposing teams or just let people get separated based on some other system (e.g. counting off, random split, clothing color, etc.)?
One can also argue that separating teams based on individual skill doesn't matter as much since good teams also depend on how well the players in the team work together, not just how good each individual is. If that's so, should there even be concern over who goes into which team?
