Good points Goober. I agree with most in some form or another. I like the self-rate ban on playoffs for 3.5 and up, too many self-rate's at 3.0 for it to be maintained to me.
I would think that if you made it to Nationals, you can hang at the higher level. I'd be surprised if someone who was even an average player on such a team couldn't hold their own at the higher level, especially teaming with their current 'mates.
