Lot of talk of finally expanding the WTC to 12 teams and finally bringing Zimbabwe, Afghanistan, and Ireland into the mix with two tiers. England seem to be wary of that, as it means they could potentially miss out on series vs India and Australia. ICC really needs to address that and can do so quite easily.
You can have two tiers or Divisions +/- promotion relegation and just allow cross-tier matchups to take place. There's actually a few different options:
You could have 2 tiers of 6, but make a system where teams play 4 series against those in their own division, and 2 against teams from the opposite division. Or you could have two shuffled groups of 6 in a random draw. Or you could have two shuffled groups of 6 with strong and weak teams alternating, and re-shuffle them every cycle.
Would also like to see the resurrection of the Intercontinental Cup, as the Test cricket equivalent of the WCL. Then the ICC can finally create a merit-based criterion for Test cricket, and a governance-based criterion for full membership.
