Yep! agreed artillery is badly underpowered compared to its historical counter-part, however, the main benefit comes when the enemy decide to go to ground in buildings, and of course forcing the enemy to come to you rather than stand off and hide behind walls and stuff.
Pre-patch the enemy would literally sit in a building until it collapsed on top of them wiping them out. Now I notice that they abandon the building at about 60-70% damage and make a suicide charge at you instead. Same result just slightly different tactic's required to handle.
Artillery just avoids having to go in after them with the bayonet.
