Well the rankings are good and bad. For those who don't know to make it to yu-gi-oh Worlds you have to top 4 a National Championship. Nat it an invite only tournament and you have to top 4 a Regionals to qualify (usually a 60-160 person tournament). As stated the rankings mean almost nothing so the + is obiovusly a bad tournament won't kill you since you only have to 4 a Regionals once each year. It also doesn't reward players who have the ability to travel or a forced to miss a tournament.

Yea, you really have to know your rulings since a lot of judges and so called "pro players" don't the rules.
