Heroes of sword or magic?

5p74, I probably wouldn't agree with you either. A Warrior still needs to go to Utopia, build up an army, and so on. And it also depends on what kind of Mage we're talking about. If it's a specialist in things like Stone Skin, Bloodlust, Resurrection, and Prayer, then Utopia is taken at the same time as the Warrior. It just shouldn't be viewed solely from the perspective of Lightning spells; a well-rounded spellcaster is often more useful. And while the Warrior is gathering forces for Utopia, the Mage can already defeat him. Here, it really depends on when you encounter them. Until the Warrior has about ten units of level 7, he's weaker than the Mage, and even then, it's not a given, as the Mage will likely have them too. Only in long games and at the very beginning is the Warrior stronger; in the middle, the Mage dominates, and between these points, they are generally equal.

As for the 4th game, I disagree with Zubr and Morni. With a fully developed Power skill tree, the Warrior gains immunity to magic and excellent ranged attack. With this setup, an enemy Mage hero is defeated in 1 turn; all that remains is to deal with his army. To be fair, I didn't focus too much on the 4th game, but tests against friends (who, thankfully, all prefer Mages) showed that I'm right. Actually, my favorite hero there is the Fire Guardian, followed by the Paladin, because he has both Sword and Magic skills.
