There are only a few games for the selection, and if teams play badly there then they miss it out. I think it would be wiser if we do that in the world cup itself. Have as many teams as possible, have 64 teams if you can, that would be better, this way if a team is losing during the group stages, they would just simply lose and not go further, same as the qualification stage where if they lose, they don't go to world cup.
In this scenario, more teams are going to world cup but losing there, instead of losing before the world cup. Still losing, still not a chance to win it, but at the very least they would be going there and it would mean a lot more money.
World cup qualifications are huge and last years. It's part of the whole process preparing for the next world cup.
That's when you actually have the chance to prove how good a team is, because you play against the other team at home and as a visitor. It's a great filter. Usually only the best qualify, it's rare to see a huge surprise because there are so many matches where you have to prove you're good.
At the world cup, there's quite a lot more of luck going on as there are very few matches compared with the qualifiers.
I prefer keeping the world cup with a rigorous qualifier, so that only the best are there. Sure, there might be some luck in there (remember, Saudi Arabia won against the current champion, Argentina), but in general you'll only have great teams there.
If the world cup allows entry to almost all the teams, then the whole thing changes, and it's not really the world cup any more, it's a badly designed qualifying stage in the beginning of it, and the normal qualifying would be a waste of time, since almost all the teams will qualify anyway.
However, underdogs and surprises are always a possibility in both the World Cup qualifiers and the tournament itself. It is possible for teams to wow the globe with their skills and abilities throughout the qualifying rounds and the World Cup itself. Teams may increase their national profile and fan base by competing in the World Cup and its qualifying tournament. Emerging nations may make a name for themselves on the world stage and serve as an example for the next generation of players by doing well in the Qualifiers and at the World Cup.
