I'm not sure if anyone else has had this experience, but artillery in DMN does not fit the old adage of "artillery wins battles." I'm not sure if it's the altered trajectories or what, but DMN artillery seems to me highly ineffective. The accuracy is such that very little damage is done. For example, I today tried a battle in which I had six batteries of elite French artillery (3x artillerie a pied, 3x artillerie a cheval; excuse the lack of accents) firing at two units of British foot. The artillery had an unobstructed view of the targets--I was playing on grassy flatlands, and there were no friendly troops in front of the artillery--and began firing at maximum range. The artillery fired continuously as the British troops marched toward my line. By the time the two British units in question were nearing musket range, the six batteries of artillery had combined for 50 casualties. I imagine this number would have begun to increase as the enemy had gotten even closer, but they would soon have been in range to begin picking off my artillerists or outright charging my batteries.
I tried another scenario soon afterward. In this one, I upgraded a unit of artillery a cheval to maximum veterancy--thus creating the most accurate artillery unit possible in the game--and pitted it against a unit of 500 fencibles. As before, the artillery was firing without obstruction of any kind and began firing when the enemy was at maximum range. When the fencibles reached musket range, they had only suffered 13 casualties. I'd have been better off just fielding a unit of militia myself, because they'd have been able to do more damage and, unlike the artillery, would have a chance of victory when charged at by an enemy.
Also of issue in this mod is the amount of friendly fire that artillery does. Artillery has a habit of hitting friendly troops in situations in which this should not occur. It seems to me that the shell trajectories in this mod are far flatter than they are in other mods and in vanilla. This seems to account for the friendly fire and for such an amazing number of shells undershooting their targets; it seems like 90% of misses are undershots.
Don't get me wrong; I like Darth's work quite a bit. I'm not trying to overly criticize. I'm just curious as to what's up with this, because artillery is almost not worth having as things stand. Am I missing something?
