Here's an example of a game on the "Ascension to Power" map. I upgraded them as soon as possible, which gave me much more benefit because the leveling process was more enjoyable. I don't keep the Imps for long because their function is to act as a shield. I don't take the Dancers into battle at all at the beginning. But I don't hesitate to take secondary heroes of other factions. For example, on this map, I found Karl and I took him without hesitation, giving the throwers to the main hero. The start was good and of high quality. Similarly, a support hero like Ingmar, Dugald, or Hafiz. So, in my opinion, the initial army of a secondary hero is not the last factor in deciding whether to take him. Of course, if Talannar is available, I will take him. Ibor's troop gathering is not a joke.
