Artillery wins battles, unfortunately it's not as sexy as tanks or infantry or easy to understand.
It would be interesting to see what genuinely good artillery gameplay would be like
Have you played Blitzkrieg 2?
It had quite simple, but important logistics part of the game.
Field artillery call-in came in form of trucks with artillery attached to them.
Those trucks could also resupply any unit with ammo.
On small maps on 1941-42 year field artillery models could fire for only about half of a map.
On huge maps (8 players) even 1945 year models could fire for half of map.
As battle goes on and you dive into enemy territory or when enemy break through your flank with light armor you should quickly reposition your artillery using those trucks.
Rocket artillery ran out of ammo in 2 volleys and should be resupplied.
When truck ran out of ammo resource it would automatically drive to closest strategic point and refill so it wasn't much of micro tax.
Hunting down truck with camouflaged elite infantry was quite real deal.
Artillery itself was as deadly as in CoH2 but also missed as much as well.
I find Blitzkrieg 2 artillery play quite good. Sadly, can't find any good video of that
