While I agree that Graham counts as a major death, Cora's death is no different from Peter Pan's, Cruella's, Hades', etc. since she was just an arc villain. As for her being a key character... yes, she's part of the origin story for Regina, but Pan is part of Rumple's, and Rumple is part of Regina's, so Pan could be considered even more key than Cora.
