I am not an expert in the Napoleonic period but do the Light Rifle units seem too powerful? I understand their increased 3 hex range but I would think that the battle dice for a unit that did not move and makes a ranged combat should be less than 3 at 3 hexes?
Often I'll target the rifles as one of first my banners - an "easy" kill with only 3 blocks to remove. Got to make it as easy as possible to get those French columns (Line Inf.) in contact with the enemy.
