That's not a bad idea mate at this stage of development for international rugby leagueI've often thought the WC should be every two years. The depth in IR isn't there. For smaller and developing nations, four years is a long time to commit to eventually getting smashed by the top-tier nations.
I think a WC every two years would speed up the development of the small/developing nations. There'll be an immediate result for prospective sponsors/investors. In four year cycle, they'll have two cracks at a WC. This is better than four years, where interest might be lost and not bother.
