Might want to consider a possible loss of honor/prestige for "one-sided" battles as well, when one side is overly superior to the other.
As an example: One side has 10K CS and engages in battle with less than 1K CS on the other side. Overkill. Not really an honorable battle. Heroic maybe, for the smaller side.
Hero characters on the smaller side might have a chance to gain honor, while the nobles of the larger army have a chance to loose honor due to participating in an overkill situation.
