Exactly, a lot of income is made from "derby games" so how do you ensure these remain? So you either need to have Welsh, Scots and US in one with Irish, Italians and Canada in the other, which means that the US and Canada dont get their "derby" and one is significantly weaker than the other.
The other thing is if there are too many filler teams in the league who are not competitive then the teams in Europe will struggle to step up. The English and French already think the pro12 is a pub league!
