artillery cluster ammo

[Wdll]

I wonder what it would be like if artillery CM only affected hex it hits directly and not also adjusting hexes. Do you think it would reduce any overpowerful feeling it has among some of us?
In my view, and this is speculation and nothing better, it would greatly reduce the amount of kills it does in a game battle. The user will have to be more careful, use proper spotters more often, and since artillery is still cheap (as it should IMO), it would require a slightly larger number of units for the same hits and it would create IMO, a more balanced usage.
All that speculation.
