What are your thoughts on the format for Asian Football Confederation qualifiers for the 2010 World Cup?

Its a lot of matches for unseeded teams to play through to advance. Its the rankings of the top 5 that bother me. I'm Australian and frankly we were well below par at the Asia Cup and I don't think deserving of the ranking we got by a long shot. I guess on the other hand it gives the teams that are expected to be there more of a chance. But a bye to the third round is very generous all the same. Not much we can do though, they make the rules and we just have to go with it.
