I'm not sure if Diana still has the "god attack" / "unleashed goddess" powers. I *think* they're going the route that it was some kind of temporary power-up (i.e. Diana absorbed Ares' godly energy projected attacks). It seemed pretty clear to me that Diana was at worst levitating and at best flying at the end of Wonder Woman. We haven't *seen* anything like that in any other film (although, how did Diana get to the island where she battled Doomsday - she just dropped out of the sky and how did Diana get from Paris to London to stop the terrorist attack or did she just happen to be in London for the weekend).
Of course, Patty Jenkins may well take the opposite approach in Wonder Woman II and have Diana soaring all over the place and unleashing goddess power blasts against foes. We'll have to wait and see in November 2019!
