Why is the strongest chess player in the world determined after many hours of play, not in blitz? - I think the parallel with chess is more relevant to Heroes than with shooting at targets.

Well, by the way, the most popular type of chess online is actually blitz. And now, essentially, amateur chess is either online blitz or correspondence chess. But that's not the point. Classical chess involves games that last an average of 5-6 hours. I'm advocating for a similar time commitment, which would be enough to play a game in the evening and to play 1.5-2 games a day in club tournaments. The current trend is towards longer games with a couple of adjournments, and the standard time control is constantly increasing - both in SoD and in WoG. I've already forgotten when I was able to play an online game with a normal time control in one sitting. Only games from blitz tournaments have fit into that timeframe in the last year. By the way, in chess, the current trend is towards reducing the time - to increase the entertainment value of the game. Not long ago, in classical control, they gave 2 hours to each player, now they give 1.5 hours. In blitz, they used to give 5 and 4 minutes to each player, now it's 3 minutes. This is just an example.
