Tactics for the Swamp (Fortress).

that's exactly what I'm saying — the best defense is having no need for it. And yet, when attacked by a faster stack (most situations), its remnants strike on the next turn — in my opinion, it's more profitable to reduce them by 30% than to receive 15% less from them on their turn.

The damage calculation formula there is more complex; 15% armor is no worse than 30% attack (the defense modifier is applied last) ФизМиг

I've already written — when calculating for a long, excuse me, "soaking" process — defense takes priority.

In cons, hives, and Dragon Utopia, contact in the 1st round is unavoidable, and capturing these objects provides a significant boost to the game, one could say — a decisive one.
