The most infuriating thing about FIFA is the constant make it up as we go along as it pertains to draws and seeding for their events. They only just decided to use the October rankings a month ago as the basis for seeding. Why are you waiting that long? It makes no sense. They learned nothing from the 2010 UEFA playoff seeding disaster, where they made up the rules at the last minute to ensure that bigger nations avoided each other (Portugal, France, Russia) by deciding that they would in fact seed them after indicating they wouldn't.
The FIFA rankings as a whole are nonsense, and still don't put enough emphasis on bigger matches. The multipliers for "match importance" in particular need significant adjustment. Not enough weight is being placed on performance in the confederation tournaments (Euro C'ship, Copa America, etc.) and the spreads as a whole need to be wider. I wouldn't even be opposed to dumping friendlies all together. The fact that some throw-away experimental squad performance can be meaningful in seeding is a joke.
Pot 1: Brazil, Spain, Germany, Argentina, Colombia, Belgium, Switzerland and Uruguay
Pot 2: UEFA (Holland, Italy, Russia, England, Bosnia and let's say Portugal, France, Sweden, Croatia, depending on the playoff and who draws whom). They will have to pull one European team out of this bunch and drop them into another pot as far as I can tell, because there are 8 groups so you need 8 in each pot. Perhaps the lowest seeded European team?
Pot 3: South America/Africa (Chile, Ecuador, Ivory Coast, Nigeria, Cameroon, Ghana, Burkina Faso, Euro team)
Pot 4: Asia/North America/Oceania (US, Costa Rica, Honduras, Mexico, Iran, South Korea, Japan, Australia)
When you look at that, you can see how likely it is that we are going to see some extremely unbalanced groups. No one on Earth thinks that Colombia, Belgium, Switzerland, or Uruguay are amongst the top 8 national sides.
