Have been reading mmo-c for a while, but this is the question which made me register here.
As the final chapter of campaign showed us, the Jailer's control over Anduin is not permanent, meaning he can act independently at least sometimes. Why didn't he commit suicude then? That way he wouldn't have had to protect the Jailer completing the ritual in Oribos which we got to see during Sylvanas fight, making it much easier to defeat/interrupt him. Is this an oversight?
P.S. I'm sorry for any typos and grammar mistakes, as English is not my mother tongue.
