The problem with Harley is that she gained an incredible amount of popularity, which is understandable because as she existed prior to all this, she was Joker's fun girlfriend and classic Harley was, at least on our end, one of the old /co/guard's main boardwide waifus. But now DC is desperately trying to make her a heroic figure in all the wrong ways, with all the shortcuts they can, because their most popular female character (Although Diana may have claimed that spot back the last two years) being a psychotic killer clown woman, the thing that made her popular in the first place, probably doesn't sit well with the powers that be. It's harder to market to normies and parents.
We've run into this situation where all of the major Gotham City based women in Batman that were once villains are now skirting the line or just outright heroes. A distinction once only reserved for Catwoman. And it's just weird.
I'm not against characters growing, personalities changing, and roles in the story changing. Especially Batman villains. If one or two get "Fixed" here or there and start doing good, it just means Batman's mantra of rehabilitating and curing these crazy people actually has some results to back it up and not just a bunch of hot air as an excuse for Batman to keep doing this shit he does.
But Harley is just going way too fast in so many directions that she's barely a character anymore. Just a plot device that nobody truly knows what they're doing with anymore.
She can't be a weak normal human in one story, then a superhuman in the next.
She can't be a villain in one book, an anti-hero in another book, and a super hero with a moral code in a other.
It's a shit show.
