How did the Serpent manage to move the Nomad across the swamp without a penalty?? The unit swapping bug was used. But why is it called a feature?? The disappearance of neutrals from a mixed army is called a bug, although it could be a feature :)

I'm talking about the rules in general. In this particular tournament, I don't know, maybe the map author is AmbekSoler and he knows his idea, but what if the tournament is held on a different map? And here, the rule that the rules of the next tournament are copied from the previous one is accepted. And already in all tournaments, the use of wings to ignore quests or the exile of upgraded units is considered a bug. Although we don't know who the map author is and what he intended. But the authors' ideas do not match the rules. But AmberSoler claims that all the bans were introduced solely to avoid violating the authors' ideas. I pointed out in my post that he may not know the author's idea himself. Maybe the author intended that you take wings and bypass his quests??? :)
