This is my theory, anyway after watching what happens in battles with mixed troops.
The top tiers have high Athletics meaning they run faster than lower tier troops. So they charge into enemy lines well ahead of their mates and easily get slaughtered since they are totally surrounded. I've seen this with just about every high tier unit that is mixed in with lower tier units. It even happens with lighter units that can move slightly faster like spearmen. Basically, your troops don't hold formation which gets them killed.
Good news... this means the simulated battles actually are simulated and not just number crunching random rolls.
