So since BM doesn't replicate real battle that well charging a 3 man unit is pointless where as real life may be good. To compensate for that, cavalry charge where they need to be should be shown by given priority to make sure they do a real charge when possible.
The same could be said of many instances. A 100 man archer unit targeting a small unit may not maximise efficiency, same with large infantry units. The charge would have targeted adjacent units if they were available, the fact it didn't suggest that your side had more then adequate forces already engaged. Why should the game ensure that cavalry maximise their charge efficiency?
