Surely, it would make it easier to have a regular promotion/relegation for an entire season...finish bottom 2, get relegated for the entirety of next season

This would also make it easier to provide a more equitable outcome for individual teams, rather than having to be dragged down(or up) by the "club championship" structure...which really is a pretty meaningless metric

As a parent, it would also help identify appropriate fee levels, i.e. pay X, get X...(as is, I can't imagine the div 2 "NPL" teams will lower their fees to a tier 2 level)
