[ТУРНИР-HotA] Diamond: Survival

As for playing in single-player mode – I’m absolutely sure that at least half of the tournament participants (or even the vast majority) played the specified format for the first time during the tournament match, without any preliminary practice in single-player mode.

That’s a valid argument. Because those who had time to practice before the tournament didn’t sign up for it, or I, for example, withdrew. The same Lizard told me before the tournament, in response to my offer to practice Diamond Survival, that he didn’t want to, and that it should be a crazy experiment right in the tournament, and that there was no point in practicing it. So, in reality, the fact that people signed up for the tournament without practicing was possibly your main chance to get people to sign up for the tournament. :D
