Why is such a complex formula needed to calculate points for WCG matches?
With such a large amount of the total years points coming from one event, it was important that all factors from each match during WCG be given proper weight. Because of this round differential, group play versus grand finals match (round importance) and current rankings of the two teams were all included. Keeping track of all of these different variables required a complex formula. The formula has undergone changes since its inception and may still need additional tweaking but currently we are happy with the point totals it produces.
