1) The new rule for a restart due to a block on Jebus. I never liked Jebus throughout my entire gaming career, I hardly played on it and didn't host tournaments on it. But when a couple of years ago I had to take on Blitz-Jebus, I immediately appreciated the scale of the problem - during that tournament, I received about 5 requests to assign a restart due to a block in layouts where formally there wasn't one, but in fact there was.
So by the next tournament, I reformulated this rule. Even the "sodovtsy" informally use it now, although the HeroesWorld rules don't mention a word about it (and where are the rule-makers looking...)
In other words, people played Jebus with the default rule for about 8 years, abused technical restarts, complained, but it never occurred to anyone to change it.
2) The substitution rule in team tournaments. For many years, everyone played with the rule "player disappears => technical loss". Until Vika thought of running his own team tournament, he read the OZV rules, thought "what kind of nonsense is this", and introduced the substitution rule.
This rule appeared in the very next OZV, albeit in a half-baked form. Now all that remains is to wait for Sanin to lose a player from the last basket, so that he realizes the need for importing the second part of the rule as well.
3) The notorious incident from Mirrors-2 about the mutual destruction of the "daddies". I saw this possibility from very far away, suggested to Sav a couple of years ago to introduce a reset of dead heroes by analogy with BT, but Sav refused. Then I wrote to Wizard and Baratorch to make such an option available specifically for mirror matches. But they ignored it.
In the end, when this landmine finally exploded, I limited this possibility at the rule level. Yes, the solution is not very convenient, I would have preferred a technical implementation.
That's why I insisted back then, because I already had a fundamental solution, the only question was the method of implementation.
In SoD, such changes occur only when Reddy pulls off something, and even then not always.
