Troops should be able to use looting to repair damage, so that you can have a "Mongol horde" traveling across the lines.
Looting yielding more gold, reducing equipment damage, and increasing troop morale in a more significant matter would make it more interesting.
Looting, right now, is only done when people wish to utterly destroy. It'd be nice to have a more balanced choice of looting options, some options which do lots of damage but little rewards, other options that deal very little damage but yield much greater rewards.
