Heroic Races for SEV?

[Baron Munchausen]

You know, this 'heroic' concept might be more signifigant if there were morale effects in SE combat. Currently, all AI forces are mindless kamikaze attackers. They keep on charging even as you mow them down. That's fine for the XiChung, but does it make sense for ALL races to behave this way? If we had actual fear and retreat when the battle was going badly, then 'heroic' could give a morale bonus.
