According to Valve, they confirmed the changes for the Dota Pro Circuit, which introduces the regional league system that will make the system more enhanced and consistent. This would also boost the support for the third-tier teams that are having a hard time qualifying in the major.
Now, we can say goodbye to the minor tournaments which will be replaced by the regional leagues and will occur in three different seasons over the course of the year. Every season consists of a Major, where the best teams will compete for points to qualify in the upcoming International.
Each league will have a price pool of $280,000 per season, which will be split among the places, respectively.
All rosters will be locked for the whole season (start of a season to the end of a Major,) without having any roster shuffles or changes. After the Major ends and the beginning of the next season, roster changes will be allowed, but this would incur a penalty of 15% decrease in DPC points.
