Is good idea, but in some sense I'm not agree.
Neutral fields will be a problem if we can not select the schedule of 1 match per round like now... and we have randome schedules that we can not change.

For the other things I prefeer a cup as I suggested last year, of 3 levels per 3. 1-3, 4-6, 7-9... and with advantadge for teams level 3,6,9... playing 1st round against level 1,4,7 and so.

I'm agree too in play for the 3rd place.
