Theres a number of problems that will always restrict the ability of the MS to implament any form of player / team restrictions beyond the top couple of divisions. Including but not limited to team lifspans, high player turnover, one event local teams (of varing ability), scratch / invitational teams, etc etc etc
Almost any form of 'classification' would be a burden I would not like to inflict on the MS untill they were in a position to implament it propaly cos as out beloved gvmt hasn't quiet realised yet the majority of restrictions / laws brought in ONLY efect those who abide buy the rules and thats not the ppl we have to worry about.
the truth of the mater is the 2 mills and move up (when it was in the rules - not now if you check) was per season so never caught half the ppl it was supposed to and as has been pointed out if you never finnish higher than the top 5 even after 20 attempts then why move up ???
If the MS is seen as the pinical (euro) of competative PB then we shouldn't worry about the 'true novice' teams either, they should cut there teeth at national events not international. !!!
theres no quick fix to this entill, like the NPPL, your in an 'oversubscribed' position and can restrict entry to teams willing to commit to at least 3 events. Then you can seed em and have proper promotion / religation. So heres a thought.
Restrict each Div to 20 teams, have as many divs as you need to meet entry, and the only way in out is by points. that way the 'team & Guests' or VIP or 4 year repeat teams will be seeded and 'alocated' to a div. whether they like it or not.
If the do well they will likely move up, Do bad and will enevitably be seeded lower next event.
