To compare to other games, they should implement something similar to league of legends. it should show all the sources of damage you've taken over x amount of time.
It might be hard to implement this in extended fights, but maybe show us all the damage we had taken, from all the enemies, in the last 10 seconds before you got knocked down then killed.
I know there's been times when I've had a full purple armor, full health, and have been killed in what felt like a single shot. I imagine it wasn't a single shot, but I died so fast I didn't even see multiple hit markers on me. Would be nice to review and learn from what happened.
