Looking at the way she's been written over the years, only confirms this. Marvel has no idea how to write her. One minute she's her normal egotistical self, and another she's hiding from Wade underneath Logan's sheets. She's somewhat of a train-wreck, as she's been written so inconsistently. Marvel needs to stop treating her like she's so sacred and consider killing her off. So they can sit back and take a break from her until they figure out what they want Storm to be. Because at the moment, she's taking valuable page time from other characters who have more potential. Such as the (more or less) restored Jubilee and Rachael.
I don't think Marvel doesn't know how to write Storm, I don't think they care. Just how little she was developed after marrying Black Panther seems to confirm this. Marvel doesn't need to kill her off they just need to take the risks with her that they have with other female characters.
