Artillery should be allowed to cause collateral damage by bombarding instead of attacking. Using them for attack has got to be one of the dumbest ideas ever, especially since they are usually too weak to defeat any units in direct combat without dying (a.k.a. being sacrificed).
For instance, how realistic is this scenario: you have a huge army outside an enemy city (or stack), and a bunch of artillery along for support. You bombard the city to reduce its defenses (so far so good). But then, in order to soften up the actual enemy forces inside, you send the artillery to attack AHEAD of your army?
Why should an artillery piece (or catapult or whatever) that is capable of hurling deadly projectiles into a city while safely behind your army's front lines be forced to enter the city all by itself and engage the defenders in direct combat? This doesn't make any sense. Can you imagine a general sending his artillery units in before the tanks?
Instead, the artillery should first bombard defense down to 0, and then cause collateral damage through bombardment, NOT through attacking. In fact, they shouldn't be attackers at all (a la Civ3). This fixes a number of issues.
1) The attacking army no longer has to sacrifice its artillery in order to take a city. Artillery groups should be used for field support throughout an entire campaign and not be completely blown away at the first stop.
2) The defender has to be more proactive in defending cities. They no longer have the luxury of camping with fortified city garrison units that are untouchable by ranged artillery and will tear up any attacking units.
3) Stacks of Doom will now REALLY be vulnerable, since an artillery unit doesn't just cause one-time collateral damage and die. It can damage the stack again on the next turn, and on the turn after that, and the turn after that, etc. until the person using the stack gets smart.
If you think the attacker now has an unfair advantage, remember that the defender will now be able to use their artillery in the exact same manner, causing collateral damage to an attacking army/stack without sacrificing the unit.
