I saw a thread on Reddit I found interesting regarding the second Final Days:

The thing about it is those that felt absolute hopelessness didn't overcome it, they died. And their souls were destroyed. The ones who overcame were those already strong, healthy.
As someone with depression the "have a bad episode? You could die AND have your soul destroyed AND turn into a monster that kills your friends and family" really hurt the message for me as it's exactly like the societal stigmatization of depression.
I firmly believe that the story was written by people with very little experience of depression/mental health as a whole. Thematically the expansion was incredibly shallow.
I honestly hadn't thought about it but, yeah, the second Final Days would've just ended up being a filter for everyone with mental illnesses. I'm sure that wasn't their intention, but still not a great message.
