Welsh will finish 1 to 8 while scotts will finish 9 to 16 and get and overall better draft.
Teams aren't going to sacrifice their whole season for the NT. Even if the occasional team does it they can't all do it every season. Even if some actually do that then at least they have something to play for. At the moment it is just boring for them with nothing to do and little sense of achievement besides losing every B3 game by 50.
I think the issues this creates are a lot less severe than the current situation. Most nations are fine but there are a few obvious groupings that would improve the experience for their managers.

That is just a start. North Asia, Central Asia, South East Asia, Middle East, whatever you call the area of the former Soviet Republics etc.
The great thing about this is you could actually add more countries like Mongolia, Syria, Sri Lankha, Laos etc, but just have them as part of the regional groups for their league competitions..
