Is there a way to switch the off RNG for combat results? If I understand this correctly, the combat results are calcultaed and AFTER the calculation is done, it adds or subtracts one for each side. I think this is a bad implementation, because it alters the combat results by a total of one point, regardless what the percentage chance was.
Additionally, if your expected casulaties are greater than 0, the RNG can give you an advantage or disadvantage. If the expected casualties are 0, than it can only be a disadvantage. Because of that, I think an expected casualty of 0 shouldn't be randomized at all. I end up having a lot of silly one point casulaties where normaly I would steamroll weak and cheap enemy units with very strong and expensive units of my own, mostly tanks against garrisons/waek corps, with expected losses like 0:6 or even higher. Losing points on these units when there shouldn't have taken any casualty at all ist really anoying and expensive.
