@SimonB being heavily involved in rugby development in Uganda I am excited by the concept of rugby across the timezones covering Europe and Africa.
However i would love within that tiered competitions coming from more regional forms. So the top competion perhaps Irish Champions, Scottish, Welsh, English, French, South Africans, Italians. All defined by highest placed within URC or domestic leagues. For stronger nations top two or even top 4. 16 teams in 4 groups being ideal.
