This kind of reminds me of Linkara's response to issue 3,(if you don't know who linkara is, look him up its worth the time) that he was disappointed because amazon wasn't unanimously supportive and Wonder Woman was born from an act of betrayal and grew up with a lie. Theres a feeling that it taints her character somehow because the circumstances to her being are not pure like it was before, that all that she had going for her is now gone, that all of this is just another darkening of comics in general. he often says that The book has "ruined" her Character.
However I think a new view of things is needed in this regard. When the world isn't as bright as some might like the light that remains tends to be more valued and worth hailing. Thats how I view Wonder Woman in the new 52. No matter how the lore of Amazon and her origin may change she never does. She's the same character we've al come to know and love, the settings just changed a bit.
Just because the world isn't as perfect as some might like it to be, doesn't mean there isn't something positive that can be gained from it. In fact it really highlights the best of whats really still good.
The only way she is coursed or ruined is if she succumbs to the darkness of her situation, which she steadfastly refuses to do at every turn. Explain that to younger fans, how despite the darker world around her, Diana is still true to form and is a beacon of making positives where there only appears to be negatives.
I wish I could put it more eloquently, but hows that help you quell your depression over her status quo?
