I think it's hugely important and I hope it gets off the ground and is a success (whatever that may be for these teams) but let's not get too carried away just yet about what this really is.
Some posters here are happy their team will be in a bigger league (obviously) but they also follow clubs that would gladly quickly and forcefully shut the door on clubs below them just as has always happened in this country.
Anyway, if you take the romantic dreams out of the equation p/r up from the nst is the ultimate goal (anyone here above thinking the SMs of the world don't want that are ridiculous). Down from there is far less important.
Sure it's sad for some tiny clubs below these 30(+12 a-league) and you can argue about competitiveness but if we have 2 divisions of 14-16 teams there's clearly enough clubs for our entire player pool (the cream of them I mean) and we can worry about a 3rd division or teams going up to the NST besides these guys in another 10 years.
One step at a time when something is this broken is all you can do
