Go to each Order leader and ask. There may not be an ATK bonus, but there are many other bonuses you may not know about. Unless one has been an Order Leader, one cannot know.
At the top of everyones page is their Order and if you click on that, it takes you to their Leader.
Order Leaders should be VERY strong in DEF since enemies get 1.5x bonus for beating them. Its a big responsibility. Making points on the front end means nothing if you are letting em run out the back door.
