Jay I just read exactly what you said and how does this have anything to do with world championships, that explains how the matchmaking / ranking system works.

I think sir must have edited the post or something cause i read somewhere about players gaining "points" for a world championship and that matchmaking was only 1 way to get these points. Hinting at tournaments etc, the description you quoted doesn't even mention what points we receive and how many are required to qualify for worlds.
