Sorry, but I insist that any format in which mismatches like NZ vs Namibia (the kind where one team has a 40 million to one odds to win the game) is the norm is foolish, cruel, a dumb format and in my book unnecessary.
I would prefer to see this sort of format instead: [Format A] Gp A is the teams seeded/ranked 1-4 only; B is 5-8; C is 9-12, D is teams seeded 13-16; Group E is the underdog teams 17-20 (based on a mixture : 55% results from the current world rankings; 45% from the three previous world cup tournaments. Each stage one group plays 4 games: SF1, SF2; WvW; LvL. One WW winning team goes up a level from levels B to E into A-D and one LL team goes down a level. Then each team's 3rd, 4th, & 5th games are played against the three other teams in their group. Yeah, I know this format does not give all teams the chance to go into the final four, but let's be honest, only very few teams could get into these anyway.
OR, even better [format B]: an annual ladder system that grows:
Year1: the top 6 teams play in Event A; teams ranked 7-10 play in Event B; two special qualifying events are held for a place in the Yr 2 group C
Year 2: the top 4 teams play in Event A; teams ranked 5-8 play in Event B; teams ranked 9-12 assemble to play in Event C
Year 3: the top 6 teams play in Event A; teams ranked 7-10 play in Event B; 11-14 in Event C; two special qualifying events are held for a place in the Yr 4 group D
Year 4: the top 4 teams play in Event A; teams ranked 5-8 play in Event B; teams ranked 9-12 assemble to play in Event C and 13-16 in Event D
Year 5: the top 6 teams play in Event A; teams ranked 7-10 play in Event B; 11-14 in Event C; 15-18 in D ; two special qualifying events are held for a place in the Yr 6 group E ; ..... the competition continues to grow like this until we have 40 teams in it or viability limits may occur .
Each event is hosted by the venue with the most commercial potential among its participants, except that once every three years the hosting is decided by whoever has not hosted it for the longest, with ties broken by favouring the commercial viability.
Overall, these formats would allow for some good, proper, close rugby, in games that both teams can realistically hope to win, making good viewing and good playing every time. It would be great. I would personally reccommend that people tune in to watch various events and not just their own one, as there would be some great action, and good viewing rugby occurring at all levels. Yes, the battle for 10th or 15th or 20th or 25th or 30th place are all great battle games that are well worth watching (a million times more so than the top 3 vs 18-20 are).
These two alternatives are also worth mentioning:
Format C: The top-seeded 12 teams all play in Groups C, D and E, from which two teams per group go forward into the Quarter-Finals; and other 8 play in groups A & B from which one team per group goes into the QF.
and format D :
round 1 of games: seeds ranked 10 v 11; 9 v 12; 1 v 13; 2v14; 3v15,... 9v20 with all teams in one big pool (with points given for opponent difficulty and for score margin of win);
round 2: 1st place so far vs 6th; 2nd vs 7th; 3v8; 11v16, 12v17, ... 16v20 in the standings so far
round 3: 1st place in the standing so far vs 2nd (game A); 3v4 (game B); 5v6 (game C); .... 19v20 in the standings so far
round 4: Winner A vs Winner B; W C vs L A (in the second tier game); WDvLB (third tier); WEvLC (4th); ....
round 5: loser of WA&WB game vs W of 2nd tier game; L of second tier game vs W of third tier game; ... and the bottom five teams unify and join forces to play vs the top team (if top team loses this they take the losing margin into the first place game; if they win it they take 5% of their winning margin into this game)
round 6: WA vs W1 for 1st & 2nd place; W2vL3 (of 3rd); W3vL4 (for 5th); ....
I think format A for 2023 and then B for all the years from then on is the best way forward, but there are many other ideas that are not far beneath it in goodness
