Spider:
I am not defending WPA here, but will try to explain how the system works in Europe.
For each World Championship each continent gets spots, and it is up to the regional federation to pick the players. For example the European spots are given by the ranking of the Eurotour. (Last year Europe had about 40 spots) (For those of you wondering why so many spots for Europe, Europe is a continent consisting of more than 50 countries. During the European Championships played this week more than 700 players from 40 countries compete)
That means that for example Norway do not have any players in the World Ten Ball Championship, World 8-ball Championship and World 9-ball Championship, simply because we don't have players that participate in every tournament at the Eurotour (7 during a year, spread all over Europe), and because of that they fail to finish high enough on the ranking.
Because of this system used in Europe, a top player such as Darren Appleton didn't have a spot in the past 2 World 9-ball Championship, or the last 2 World 8-ball Championships, and was forced to play the qualifiers the week before these tournaments. And those qualifiers are HARD. Last year, WC 9-ball 2007, 160 players from 23 countries participated in Manila for the last 10 spots. (so does this mean that the World Championship had 128 players + 160 from the qualifiers, which is about 275 players?)
Was Darren good enough to participate? Of course! He's even good enough to win the tournaments. But the rules in Europe are made in stone - if you don't participate on the Eurotour, which is open for any player from all over the world (
www.eurotour.nu) (or finish top 8 in European 9-ball Championship), you won't get a spot.
I think the system for Europe is fair, and what is even better with it, it makes a strong tour! The Eurotour has almost 256 players on every tournament. (Darren has been forced to compete on the eurotour, and his reward has now been some great results and $$ + now he is high enough on the ranking, so he's in for the next Championships)
Now it is up to the players, tours, organizations in USA and North America to get together and decide how they will use their spots, and make it known to all players minimum a year in advance.
Tournaments like the World Championship can't be open to all players. It has to have a limit, just like the US Open, who has a limit of 256 players. They need to know in advance that they can finish the tournament the day they have said the final will be played.
Perhaps 128 spots on the WC are too few, but then one of WPA's "sub-federation", for example BCA, can ask them to make it 256 instead...
EDIT: with the system used by Europe, it's no doubt that Europe send the players that have been performing well the last year, and deserve a spot. If a former European Champion doesn't play good enough anymore, or doesn't compete as much as he used to, he's out. You need to perform well to grab a spot from Europe!
If every continent had for example 7 open tournaments with 256 players on every tournament, and when the season ended they sent the top 32 players on the ranking, no one could complain about the "invites", because if you want to play the World Championship you have to play on the tour!
