Okay, Pyrrha was a great character, yes, but her death had a point and purpose. It was meant to show off how powerful Cinder was compared to other characters, and her death brought character development to her teammates, as well as to Ruby who had the bad-luck to witness it. It had a purpose, and I feel as those bringing her back would nullify it.

Of course, if the creators decide to bring her back, I'd be okay with it, but it should be their choice. We, as fans, should not harass the writers of the show. They should be allowed to take the story where they want to take it, and if that means leaving Pyrrha dead, so be it. Life isn't fair. Not everybody gets a happy ending.
