CTPAHHuK, not all games were played at the World Championship 2008. Therefore, not everyone will be in equal conditions. I think each portal is capable of determining the level of participants who represent it.

Players do not belong to websites and only represent themselves. There are people who do not play on any of the listed resources; who will determine their strength? And who will take responsibility for ranking them? Plus, there will be more behind-the-scenes maneuvering. Let everything be open.

Here's a suggestion: essentially, the first round against bots is a qualification round, but a random one. Let the bots target the seeded players first. This will minimize the randomness.
