Round table

It's not about the four-sided maps. Here's another example. Let's say the game is on a popular map. The Guard Tower is in the elevator. On one side, it's an easy target, like Hydras, and on the other, it's guarded by Phoenixes. Let's say one of the players kills the Hydras, and on the other side, the guard is moved. So, he's sitting there, waiting for the right moment to take the Castle. I don't understand why the moved guard should fight according to the rules, but this advantage isn't.

You're getting something mixed up. First, explain what you mean by "sitting and waiting" - what's the meaning of that, and how would it look? Do you think the opponent can already see the Castle from the Guard Tower, or what am I missing? Second, the second player, whose Guard Tower is moved, isn't blind either and sees that it's moved. He can also see the opponent emerging from the teleport for a second (by the way, moved Guard Towers don't usually appear in elevators) and can see the opponent's moves on the visible territory in War Trials. So, it's unclear how this obvious trick would work, and even if it did, you need to be prepared for the Guard Tower to be attacked, and the player who attacks the Guard Tower early has the right to certain bonuses. So, stop overcomplicating things
