Wrong. Luxembourg is even tinier than Croatia. Norway(4.6million) and Finland (5.2million) combined are smaller than either Belgium (11million) or Czech Republic (10million). Not to mention they've produced fewer top 100 players combined than each of the latter two.
Tradition is not enough to save tournaments. The world moves on and calendars have to evolve.
No, you used richer as a reason Croatia and Romania shouldn't have events. Those 250s well they get enough crowd numbers, sponsors and pay their licence fees hence they are still there.
Same as Canada, the venues are up to TMS standard, they get the people to the venue along with the other revenue, unlike Shanghai which has no crowds.
