I'm already so irritated by the fact that you can't really exploit the terrain in Napoleon TW to your advantage. You just have to be lucky. Numerous times I tried to lure the enemy or approach the enemy from behind or from the flank (on the campaign map) so the terrain would provide me with some advantages. Almost impossible and annoying!
For example: I attack Vienna with a huge army. I enter their region and I'm out of moves. I know the next turn their army will leave the city of Vienna and make contact with my army so I do my best and 'study' the terrain and place my army there where it would have an advantage over the enemy (on a hill fo example). So I see some hills there and I put my army as accurately as possible on top of the highest hill (if there even is one, because campaign map is nothing like the battle map) and wait there for the next-turn attack.
Ok, they attack me, we go into the battle map and guess what! I have to organise my army in a valley instead of the hill top I put them on. And most of the time it's just like that in the game!
CA needs to assimilate the terrain on the campaign map more to the battle map AND do something else too, so that the terrain on the campaign map is, let's say, more 'visible'. You can't really exploit ridges or mountains or such in the game (by those I mean really really good advantages over your enemy who will need to storm the high hill). You can't exploit such terrain (you COULD in Rome TW, Medieval II TW...) because what are the chances that you even come across such terrain. Even if you do manage to fight a battle from an advantageous position, it is because you were lucky.
