NC doesn't work, not enough active players to do it properly where u can involve more of the community by having divisions and multiple teams per nation and shutting out half the community at this stage is pointless.
Fantasy league over scramble league because scramble just has people leaving because they don't like their team (yes this happens in fantasy but not to the same degree) and warband players are too anti social for it. At least in fantasy they can have a good chance of being in a team with a friend (ooo warband friend!)
So i guess best thing is either normal league or fantasy and idc which. (Either that or make up a new format)
