Well, that's the way it is. And I also wanted to save my swords.
I agree, that was the intention, but with the army I had, the Angels, with your arrangement, simply refused to attack the 16 Pikemen and instead killed the unprotected Champion.
So, depending on the number of troops, a specific tactic is determined in the "Angels" scenario with the arrangement. And it's impossible to guess in advance until you test how the Angels will behave.
In the future, I will try to post short tasks from online games myself, with a prize pool, for those who excel in solving them, and I ask Heroes players to also post tasks.
