I was specifically talking about its effect (or lack thereof) on who advance to the next round and who doesn't. Also how one country advancing is totally dependent on another country (whom they have absolutely nothing to do with) winning or losing. Confusing.
Which is patently true for just about any sport that has group play, except you may need to swap country for franchise. Also, getting rid of ties doesn't affect this specific issue.
Not sure what your point is, but perhaps your preferences are better suited for tennis or something similar.
Exactly. I also don't see why it is so difficult to understand. Points are first. If there is a tie, it is goal differential (which is clearly in the standings). If they are still tied it is goals scored. After that, it is points in the matches for all tied teams, then goal differential among the tied teams, then goals scored in the matches among the tied teams, and finally drawing of lots. That last one is obviously not ideal since it takes it away from the field, but you have to do something.
If you look at the tiebreakers for the NFL, they are just as complicated. The NBA is actually pretty complicated as well. MLB just has a play in game, but that is pretty much impossible in the World Cup.
In other words, tie breakers are complicated in pretty much all the major sports. Soccer really isn't any different until you hit that last one (the drawing of lots).
