If you have excess Dragon Vein points, the statues you put up and upgrade in MyCastle can increase stat caps slightly.  Visiting other castles, leaving feedback, and fighting is a good way to get DV.

I meant how to max their stats, after you have hit the max level, since reclasing keeps you at the same level. I know about the statues. (Tip, they can be used defensively in Castle battles)
