Fire and Flee???

[Mokurai]

My recommendation to the devs would be that Fire and Flee works as it does now, with the ordered units routing from the battlefield.

However, they wait in that state until the battle as a whole is resolved. If the owner of the F&F units wins, the F&F units stay in that province.

Alternately, since the F&F units are at least in theory retiring in good order, perhaps instead of randomly sorting them into neighboring provinces, the whole group should rout to the same province.
