\ Fail thread, Auto assign does not assign players based on their stats or skill level, it merely, assigns someone to a random team... I fail to see how you believe this would have any effect on the team balance, other than leaving it " up to chance ".

There is  only three solutions:
A) Plug-in auto balancing program.
B) People with ethics and morals who balance themselves.
C) Admins to balance teams.

B is obviously not an option, C is becoming an obvious problem,  A is the only way to guarantee there will not be a problem.
