In the third game, I always thought that the Necromancers were stronger. But once, when I was playing with a human ally (I was playing as Necromancers, and he was playing as Humans), the Humans showed themselves to be stronger. He was able to handle those who were too difficult for me. But there were factors at play here – he had diplomacy. Although, I was raising free Liches. And still, only through our combined efforts did we complete the map (he took my Liches and, with their help and his army, defeated the enemy). So, the question is debatable. Necromancers are strong, but Humans are often given diplomacy. And then...
and Necromancers also get diplomacy + free Liches!!! and then...

No, no, no matter how you look at it, in the 5th game, the Necromancers became much stronger than in the 3rd. And if you add "combined super artifacts," we will be invincible. This is facilitated by many factors, for example, raising Archers, which, as you remember, was a fairy tale in the 3rd game, only by collecting the King of the Undead's Cloak – which is an even bigger fairy tale (I personally collected it only twice)...
and they raise not only Archers!!!
