This last Monday night in the AvA was setup for OddCAF's Monday night Midwar furball. Two sides with the usual one side good rides other side garbage rides. Good side call went out and the darbar reflected it for awhile. So the CM gave both sides the same plane set. Fun petered out pretty quickly when everything was equalized and the garbage men started doing the spanking in good side rides.
You always have a large percentage of the MA who do not want to play with even odds and a very tiny percentage who like going to a 12 on 1 gang fight with a tooth pick against baseball bats. A two side night would end up with a few guys who like tooth picks versus a hoard with meat seeking nukes. If side balancing of any kind was imposed, people would log for the night and simply avoid Tuesday nights.
If you have to impose on the MA what players choose to do, they will leave until the MA goes back to freedom of choice. And if you were given your own arena with this wish setup in it, no one would show up. So this wish requires the power of Hitech to force players to do what they are not paying for. That could cost him customer good will and money, in the end what will the business owner vote for?
