battle standard should do average damage like it does in current version, but it need to have stronger moral effect, an extra skill perhaps.
for now, its like the old yes captain perk, it helps player save one perk point, but cripple one second line roll as well, specially in mid/ late game when you obtained 2 legendary polearm in your inventory, and you have more than 2 sergeants in your row, time for flags get retired.
