Recently, quite a few countries have been dropped from the list. I don't see anything said about that as to what is the reason for that, although I'm sure there is a process that is gone through in determining who is eligible either way.
Because the number of games played is important on where a team sits on the ladder, it doesn't always reflect the level a nation is playing at. Looking over several years does give an idea of how a country is progressing or regressing.
