These rules will create a lot of debates in the coming days. If one team is to be selected from Asia, it would be India. So no chances for Pakistan, Sri Lanka and Bangladesh team to be in the Olympics. Also if Australia goes to the Olympics, the New Zealand will have no chance and it will be a big set back for them. From Africa, it would be South Africa of course and England will be playing from the European region. One team will qualify through the qualifier tournament and that would be a tough competition indeed.
The debate has already ongoing, most people are not taking it well.
If, rather than the top ranks from the continents were to be mentioned in such a way that seven or ten countries would be allowed to participate, it could have been the top 7 teams or starting another tournament to qualify.
If it were done this way, I think it would be fairer and most people would welcome it, because the way teams are currently selected can actually be unfair.
