Sure, I was just exploring the reasons why it might be hard for the wrong reasons. Even still, the AI will do everything in its power to lose, like attacking the Hero with light cavalry. With careful positioning you can neuter the Taira with just your starting units even.
I believe it's extremely difficult to outright lose the mission, which is what makes it an 'easy' mission, even if you reckon it's long and tedious (it doesn't have to be though, see pic).
