I also was thinking that a commander rule option might be nice too.
For those who aren't familiar with it, it's in the board games optional rules list.
Basically, once per turn the attacking army/commander can manipulate one die of a chosen roll to change an outcome. This is to reflect the influence of the commander on the field of battle and definately wouldn't hurt to slightly curb the advantage defenders has with the dice rolls.
Those of you who have had 10 armies widdled down to none against 1 defender know what I mean. Anyway it would be an option and definately a new dynamic to the game.
