You're almost definitely not getting griefed. The healer is just paying more attention to your rapidly dwindling HP than your list of buffs, and is burning all of their resources under the assumption that they're preventing a wipe instead of causing one. They might not even know what Living Dead is.

Is this situation your fault? No. You're (presumably) using your job's kit correctly, and other players' misunderstandings are causing problems. But telling the healer what you intend to do before you pull, or civilly explaining Living Dead to them after a wipe like this, will probably get you better results than going to the forums and posting about how Square Enix needs to "step in" and "tell healers enough is enough" because...healers are making mistakes in dungeons?
