Several players, such as Ronnie O'Sullivan, Mark Allen and Steve Davis, have warned that there are too many tournaments during the season, and that players risk burnout. In 2012, O'Sullivan played fewer tournaments to spend more time with his children, and ended the 2012–13 season ranked 19th in the world; he played only one tournament in 2013, the World Championship, which he won. He has suggested that a "breakaway tour" with fewer events would be beneficial to the sport, but as of 2018 no such tour has been organised.
