your questions regarding the game rules (improving the interpretation).

Here's an example with a picture: when Golden Dragons and Ifrits are in the same passage, standing together, you choose which one to attack first, the one with wings or the second one. But here, he flew past the mountain spawn point, went through the treasure, and broke the Vision. Even if there were other units standing with the Vision, he shouldn't have flown like that (the point of view of those who think Dark is wrong).

You are all looking at the situation from the perspective of common sense. But you need to look at it from the perspective of the rules, old or possible new ones.

In the rules, it is very difficult to correctly formulate the difference between flying on a Vision from left to right (as Dark flew) and flying on a Vision from top to bottom (as in the other screenshot with the Ifrits).

In order to introduce a strict and clear concept of "illegal scouting" or "illegal moves," it would require a lot of text, and even then, there is no guarantee of the result. And even if such a rule correctly describes Dark's situation, it is not a fact that it will describe other similar situations just as correctly.

That's why I say that the rule should be simplified.

This does not negate the fact that there was a violation in this game and an incorrect decision by the judges.

It depends on what you consider to be the "judges' decision." If "Dark's action is allowed by the rules," then yes, it is incorrect. But if "Dark's action violates the rules, but it is not necessary to punish him for it," then it is correct.
