What I think bugs me about Sanctuary is that Tom King included some modern therapies for PTSD, like exposure therapy, but did so in a extremely simplified and simplistic way, from what I can tell as a layman. And also that not all mental issues are PTSD, not even among superheroes. The one that Superman exposed most certainly isn't PTSD. And Arsenal might suffer from PTSD, but it's complicated with addiction, and would thus need treatment of both.
