Suggestions Regarding Damage Taken Measurement

For the damage taken graph after each match, I doubt this is the best way to represent the amount of damage absorbed by each player since it only shows damage taken after the armor/MR effects. The data showing right now definitely helps but when it comes to summarizing things like "Did our tank really take damage for us?" or "Did our adc get focused so bad?" or questions like these, current measurement does not work so well in my opinion. For example, in a particular match, blue side tank wisely builds a Thornmail to counter the adc who is 10/2/5 on the purple side. This in case, the tank takes less damage but actually very helpful for the team. If he still dies a lot in team fights, he might be to blame for not taking enough damage according to the graph shown after the match. I don't have a better idea right now but I think this damage taken measurement needs some improvement.
