It's not that tough actually. They just need to let the big teams play more matches between themselves through 2 or more team format tournaments and allow the lower ranked teams to play in separate tournaments between themselves.
This is basically the whole 2 tier system which I completely support since it is the optimal balancing act that you spoke of.
Tournament? You meant the tours?
But we have WTC in the middle of this, the system is designed to include as many teams as possible with 6 tours each and the teams with top 2 winning the spots for finals based on percentage of points earned with number of matches played so the system need to be changed because currently it included top 9 teams eligible for WTC cycle.
