I've been trying to work that into a fic for ages - Diana meeting Shiva, and Shiva being all "if you should ever lose your powers, amazon, be prepared. I will find you" (and Diana being like "... Dinah, your friend is insane, I hope you know that"). That would be one of the few cool things it's possible to do with her current state; set her up against Bruce and Ben and Shiva and demonstrate that it's really, really, really not just the superstrength.
(In fact the superstrength is probably a hindrance; that scene in Birds where Dinah beats Diana in a sparring match, it's always struck me that Dinah had an unfair advantage. She can go all-out, but Diana's paying as much attention to regulating her speed and strength to human levels and not letting Dinah get hurt by kicking too hard against bones that make steel seem soft, yielding and breakable as she is to actually fighting Dinah. For someone as talented as Dinah I bet that's a heck of an edge.)
