I agree that while the autobalance currently is done by sheer numbers and mathmatics, that it should offer a ranking option to compensate for the top 4 people that have a score of 25 vs the opposite teams 4 top people may have only scores of 12-15 which is unfair for the teams OA stats.
Yes, you can do it manually but that is really a P I T A !!!
Just my 2 cents
