For the good of the planet (as well as increasing the number of tier 1 vs 2 matches) international rugby should be kept as regionalised as possible outside of World Cup years. The All Blacks, Wallabies should tour their South Pacific neighbours in alternate years (and actually play in Suva, Nuku'alofa and Apia) as well as hosting the same opponents in-between. Japan and Hong Kong could also possibly be added to this group. An Americas tournament between Argentina, Uruguay, Chile, Brazil, Paraguay, USA and Canada could be played home and away over a two year period, doubling up as World Cup qualification for six of the teams. Likewise in Africa with the Springboks, Namibia, Kenya, Zimbabwe, Ivory Coast, Uganda and Madagascar. The 6N teams could alternate three-match European tours to Portugal, Spain, Georgia, Romania, Belgium, Netherlands, Switzerland and Germany
