Essentially, that's how you have to play, only I try not to change the troop type (due to morale and gold). But you got the point – you can't do anything without a fighter; a tactician or mage won't solve the problem in such situations. Sometimes you even have to deploy an attack stack, if, of course, you get a gold mine or a passage in return. It's bad when you can't afford to lose a hero, but you don't have enough gold yet... Or if there are several different monsters – one defeats you, you resurrect, the second attacks, and you can't resurrect anymore – no chance.
Of course, if the AI tells a scout that it will be defeated, it means that with skill, you can, on the contrary, crush the enemy, and even with minimal losses – you assess the enemy's monsters and heroes, choose a tactic, and destroy them. But if there's no answer to a problem, no trick will help until you find your own solution.
I once read about tasks on another site, about defeating much stronger armies, even without losses, and I tried to solve one of them several times, but I stopped trying. They were right that a lot depends not on skill, but on luck in the game – what kind of battlefield you get, how often morale appears, what kind of damage you get, etc.
