They’ll probably do it like in Heroes 4, where warrior heroes could learn spells, but their spells were 50% weaker than those of mages. Well, they could leave the guild system, but make it so that you can learn spells for skill points. In principle, the dragons in the castles were made too weak. In Heroes 3, you can see how much stronger the neutral dragons are compared to the tamed ones. And as bosses, they are the most suitable in terms of size. Unlike the bosses in King's Bounty – huge spiders, frogs, etc.
I disagree here. Both the spider and the frog were very good as bosses. Although they shouldn't be copied into "Heroes." I think they will make the dragons just strong enough so that they can be defeated even in the early game. Otherwise, such monsters in the army will destroy the balance. And as strong bosses, I would like to see the leaders of the factions: small in size, and impossible to hire. Unless, of course, these brothers and sisters will be pitted against each other :). And most likely, they will.
