Not necessarily. You could have the top 2 in SL compete with top 2 from the NRL in an expanded WCC, and then the remaining 8 SL teams go with the 8 French teams into a cup comp. 4 groups of 5, gives everyone 3 home games, with 2 from each group going into 1/4 finals, etc. Means the clubs get the games they need financially, but also with some variety.
Too many clubs unnecessarily excluded
