The quality of the County Cricket is not high enough to help prepare players to a high enough standard to help the England Team to regularly challenge Australia and win the Cricket World Cup.
I think there should be 2 divisons of 7 teams with 2 promoted and relegated.
Pehaps Derbyshire and Nottinghamshire should be merged into one regional team.
Less teams means a higher concentration of the best players in the each teams and this will help force up domestic standards and better prepare players for England matches. quality instead of quantity.
After all Australia has less than 18 teams in it's dometic cricket championship and I think this has helped them along with having naturally good cricket players to domiate world cricket and to win the World Cup 3 times in a row.
