I think that he meant that WW gained all her powers to be a "prefect match" for superman at least on powers.
Diana has problems killing her enemies, that's why she always prefer mercy with her enemies. Now if there is too much at stake it can happen. But superman and WW still have closer personalities
i'm ok with it. But I would like her to win her skill to fly somehow.
Powers don't make anyone equal to anyone. I can do without flight, mostly of the new Gods doesn't have the ability to fly.
