That is actually true, I forgot the deflection damage.
Will redo it, potentially this evening if I find the time
How are deflection shots implemented? As straight values or percentage of the base damage? I know for the ISU it should be 120 smg per shot
percentage of core base damage
AP has 120 deflection damage
HE has 40 deflection damage
Skill shot has 80 although it has high penetration values and few units can bounce it.
If I remember correctly skill shot can also be used to reduce TTK if used after first shot since it has lower reload.
ISU-152 is probably good AT vs up to including the Panther and vs higher armored the skill shot and 120 deflection damage is not bad either.
