A THREAD FOR NEWCOMERS!

No. The point is that I, for example, like the fact that the hero initially has Tactics (which is usually rarely found in other heroes), but leadership is not useful to him at all. It would be more relevant to have Attack or Armor as the default skill.

Then these heroes will suit you - Gunnar, Charna, Lakus, Tyraxor, Shakti, Das, etc. Buy any of them and level them up. In online games, they do just that, playing as a specific faction.
And if you want to edit the skills, you can do so through the map editor. Map specification, Heroes tab.
