There should be 8 teams in it, with no quarter-finals, obviously 2 groups of 4. Top 2 in each into the semis. 5 weekends is enough, as we can't play 3 matches in 9 days. It takes 4.6 days to recover from a RL match.
2017 WC :-
Gp. A - Aus, NZ, Samoa, Tonga
Gp. B - England, France, PNG, Fiji
Tho of course I want Europe in there instead of Eng. and France. So maybe Lebanon would play, obviously there would be qualifiers, but as there are club teams in the USA & Canada, and league there, I'd only want to see players in those leagues playing for the US and Canada meaning they probably wouldn't qualify. Lebanon would probably play against the Cook Islands for the final place, or possibly S Africa.
