Nagan has the same stance – to gather a large group. That's why he distributes quotas left and right. I don't agree with him, but since he's the organizer, it's up to him to decide.
In my opinion, 16 people and 4 rounds would be optimal. Without tourists and casual players, only strong regulars. Different quotas for different qualifiers (based on the strength of the team and the number of people who want to come). So that there is competition in each qualifier.
Why even hold qualifiers then?
You currently have 8 finalists from St. Petersburg and 6 from Moscow.
Are you deliberately undermining the prestige of the final? ;)
Although, as the organizer of the first CIS Heroes tournament, I'm pleased that everything was done correctly in the first tournament – a strict selection, regulations, 18 players, and 4 rounds.
