I'd love if someone had insight into how casualties calculated. For example, I just had a (very long) battle where I noticed the following.
Our two sides were generally evenly matched, but we had the slight upper hand. I was attacking.
When the defenders hit our longbows, we would lose 16 units. None of our units were heroic, they were all regular.
When we hit their longbows, they would lose 12 units. This happened when our strength was 3200, and theirs was about 2200. And these were at HEROIC stance.
When we hit their phalanxes (regular stance), they would lose either 3 or 4 units.
However, when they hit our cannons we would lose either 2 or 3 units. (regular stance).
Anyway, the entire process of how casualties are calculated is completely bewildering to me - I'm thinking it might have something to do with production cost (why we lose so few cannons when hit), but that is pure conjecture. And it still doesn't explain why we would lose more longbowmen than the defenders, when they had the heroic stance and we didn't AND we had greater overall strength.
Perhaps it is a glitch in the game or something but it just doesn't make sense.
