P.S. "Wait," as well as retreating into a defensive stance, doesn't save the situation, because in a one-on-one battle, "Wait" is not needed by the slower unit, and "Defense" will be applied only after taking damage, and the fact that it only works until the end of the round makes this tactic completely useless.
Please, don't spread confusion, Sir!!! )) The "Defense" order works perfectly until the next turn of the creature, not the next round of the battle, and it provides a significant defense bonus - 20%, and not just its own, but a cumulative bonus with the hero's defense! The Titan, by using the defense order on its turn, will take less damage to its head in the next round than without defense. Check it on Nagas (speed 7) and Hydras (speed 5), both heroes without any parameters, of course, the terrain is grass, let the Naga attack the Hydra - it will take 28 damage. Use the defense order on the Hydra. A new round will begin, the Naga attacks, and we see 26 damage. Q.E.D.
Regarding the topic: the topic, although it will guide newcomers on the right path of mathematics and other things, but when they start searching for information themselves, such topics will no longer be needed, but for now, unfortunately, newcomers are characterized by a lack of initiative; they need everything to be told and shown... this is not a criticism, but a call to be more independent!
