To be honest I wouldn't mind if you removed death recap functionalities
So long as you just give me the raw numbers of damage type.
I don't need to know Renekton's Q did 400 damage to me, autoattacks did 352, and Thunderlord's did 172.
I just wanna know
Renekton - Killer -852 physical damage -231 magic damage -53 true damage
Flanked by the two most damaging other sources, whether they're champions, minions, or towers.
It gives all the important information. Who is doing the most damage, and what type of damage I'm suffering from. I don't need to know how much damage I'm suffering from in a specific amount of time (in 90% of cases). I don't need to know his items because I can just tab and the items are there. It's that simple.
Side note: this would measure all damage taken in a specific time frame up until your death. Maybe 10-20 seconds.
