I don't agree with this approach. I think the issue here is that unless you have your AT guns or tank such as a panther setup in position ready to immediately cancel the barrage, the "shotgun" part of the barrage still acheives its purpose, likely targeting those AT guns, or MG etc. Basically I think that the idea that it gets canceled will not arrive fast enough before the damage is done.
I hope the calliope is addressed in the future in some form, and at the absolute minimum has its front armor lowered from 160 -> 110. Similar to the jackson, this unit has no reason to be bouncing shells from p4s. Other adjustments would be welcome, maybe HP nerf with a price reduction etc.
