I saw my first "man of the hour" a few days ago in a Brutii campaign. I never auto resolve (way too dodgy) even if the odds are only a single unit of peasants. My captain won two consecutives heroic victories against the Dacians. They didn't even outnumbered my army, I just lost very few men. In some other campaigns even though I won numerous heroic battles (sometimes outnumbered 2 or 3 to 1) with the same captain, bur it just wouldn't do...
