Savior health ratings
Does anyone have a understanding of how the savior health levels work in the current challenge? I just had an example where a level 22 savior had taken several overwatch 100% interrupt shots from my three survivors and when I checked his health level, there was only 22 left. One shot from my level 18 legendary shooter, no kill. Second shot from my level 18 legendary hunter, no kill. Third shot from my level 18 epic hunter, still no kill. How is this possible? Thanks in advance for any explanation.
