I must raise anew the question: Heroism on heroes, yes or no?
My vote goes for no, Heroes can't be "more heroic" compared to troopers than they are at level 1. Plus, it spoils the game. You should nurture them into greatness, not cast a one-time spell and roll-over. Plus, if we change the way the experience is gained, the heroes in the first line will raise quickly in levels - good. The heroes in capital will have hard time, which is good as well, it stimulates the non-conservative, adventurous style of play.
