My medusa's are getting Assassinated by lower Ambush units

[tabanli]

I have my medusa's at the first in battle line, I have more assassin than my opponent and I just keep getting ambushed. I thought that the ambush would cancel each other but apparently it doesn't. This is not a bug but I think the cancellation makes more sense.

It only cancels if they are both successful in their ambush roll.

This is not a bug but I think the cancellation makes more sense.

Why? Both units try to ambush each other, and either one may succeed.

Consider a situation where the difference is small: an Assassin with 70 ambush against one with 75. It would make no sense that only the latter one would receive an ambush chance!

Yes this is not a bug but intended functionality
