Maybe it's time to decide and rewrite the rules? Almost half of them are outdated. Is it really necessary to make things difficult for newcomers?
As a judge, I think you should first and foremost be fair. If players are exploiting the rules through technical means, they should receive a blue mark.
Firstly, Chemist is definitely not a newcomer, and secondly, I am not a judge in the tournament and, as an interested party, should not have made a decision. And I can imagine the list of players with a blue mark :D
Once again: the rules either work fully according to all points, or they are simply unnecessary.
After all, there was a clarification in the rules: "if it can affect the outcome of the battle," who is it for?
This point is not applicable when attacking a town/village.
