Yep, this is NOT a new topic and the Jokers views, and many others, are well noted against such a new venture, and for traditions sake that's understood, and tradition is important.
A view is to have divisions that group relevant performing schools in divisions, possibly by age group or maybe it starts at a certain age level, with a promotion/relegation each year.
The current trials period, where typically the GPS play the CAS and ISA schools, then the GPS play their own 5 GPS games, could become a 12-16 game comp that covers all the games of top 6-8 schools, likewise in the other divisions.
Within those 12-16 games the best performers of the GPS ,CAS,ISA etc win their own associations comp, same as current, but in the end, there is an ultimate winner. (which has often been a discussion, as to which school is really the best)
Such a grouping should also make games closer, more enjoyable ( as opposed to being flogged each week), and ideally safer for those involved (as teams are more evenly matched).
I am a CAS person, but hope this just opens up discussion.
