*As always this is only a suggestion, the leagues listed are in order of importance, feel free to run as many or as little leagues as you think your system can handle. The setup above gives a nice regional feel.
It is advisable however to run as many top tier leagues of major nations as you can to keep the continental club competitions competitive
