I'ma give y'all the benefit of the doubt and assume you kinda skimmed over the relegation/promotion part of the MAO review--and since it's important (to me and all right thinking peeps) I'm taking a moment of my valuable time to address this topic specifically.
Right now 2 teams are relegated from the Champions division every event and 2 teams are promoted up from the Challengers. The current process is dramatic but it doesn't really fit the claimed league intent, which is that the Champions division consist of the ten best teams in the world that event. But just because the league relegates the 2 lowest Champions there's no reason to believe that teams previously relegated are better than the teams the newly promoted are replacing. It's simply that if 2 go down 2 gotta come up and right now they make the biggest deal out of the 4 teams fighting on Sunday morning to stave off relegation. All that really does is give the prelim bottom dweller(s) one last chance to avoid being relegated but it seems to me more of a spectacle than a system guided by competition or the league's stated desire to see the 10 best teams compete in Champions.
What the league should do, beginning in Chicago, is simply take the bottom team from each Champions bracket and match them up with the top 2 teams from the Challengers. If the Challenger wins then that Challenger is promoted and replaces the defeated Champion. If not, you reaffirm for the time being that the ten best teams are the ones that are currently competing in the Champions division. In you want to be the Champion you have to beat the Champion--and those match-ups will be a lot more exciting than pairs of Champs fighting to avoid relegation.
Promotion & relegation is a good idea as is the Challengers division but this is a better way to implement promotion & relegation than the system used now. Tell the PSP you favor head-to-head Champs vs. Challengers.
