Thanks for the correction, I'll try and commit it to memory.
Still very much not cheap. We just had a page of "you can't count on the Brummbärs bunker buster because it's a muni sink" so bringing in an even more expensive ability to highlight the isu AT seems a bit odd.
There are few difference:
The guy was comparing the barrage ability with auto fire and that is simply misleading.
The ISU-152 shot is vet 0 the barrage is vet 1.
What I have pointed is that if deflection damage is not enough vs high armor target one has the add option of using the skill shot that has higher penetration.
There have been a number of posts describing the AT capability of ISU-152 as bad. I have simply pointed out that with high damage, decent penetration, deflection damage, skill shot and access to mark target describing the AT performance of ISU-152 as bad is simply wrong.
