The Bane of My Existence

So I've been hoping to get Myrrh for a while. Like a few months back awhile ever since I got an extra hector from the distant counter banner. Finally got her, only problem is her -def+hp ivs. Not to mention that the defense bane is a superbane, I'm wondering if I should stick with the dc,qr iote's shield build I was planning on doing. What are your thoughts?
