I went in and poked around with the legacy setting... didn't feel right or maybe after almost a year of tanking (pld only one at 50) im probably way to used to the default.
In your last paragraph you explain perfectly why we need this. I too just swing the camera to face me (with the mob in the foreground) but if there is multiple mobs and i lose hate they run outta camera and while most of the times its no big deal and i scoop them back up... sometimes it can turn into quite the camera battle (meanwhile everyone dying lol)
