It's really annoying how I have zero idea of how the tactical side of the battle works, it just seems completely luck based if you told me it was just picking a random outcome regardless of the combat situation and how many supports, what units on what terrain didn't matter I would believe you. I don't think that's the case but in liue of any evidence as far as I know it's completely possible, if it is some kind of dice toss just show it Im fine with getting unlucky if I know what the variables and odds are.
