50% winrate is boring and transform tournament into resource mining.
As I suggested few month ago it’s better to reorganize it to Year based tournament with current system where at the beginning players sorted by GP and then climbing higher as the can to win great year prize. And then it starts again with sorting by GP and year of new tournament.
In this case no reason to lowering GP because it matters only for 1/12 matches. And every year will gave some new experience than just 50% winrate. Also this will remove GAC squish questions.
