I would like Damage Taken post game stat replaced or accompanied with Damage Absorbed
pre-mitigated damage taken
Habitually I look at post game stats. And it's nice to look at stats that are as relevant as possible.
If you play a tank being able to see how much damage you absorb pre-mitigation would be a better story than good old "damage taken." This means your character's tanky resistances is included in how much aggro you may be tanking in game. This would give tanks significantly bigger and more representative charts of their damage sponging effectiveness than whatever amount of hp they happen to have more in their build taken every fight.
And if tanks are graded by damage taken (not sure on this one!) it would be a more accurate metric better accounting for their resistances.
This way if double mobies Draven runs it down mid repeatedly his damage absorbed statistic more likely is a much different story than Malphite trying to carry the team with his complete tankiness in a tough game.
It would give your post game stats much more of a "wow factor" after a really tanky game where you find out you absorbed more damage than the rest of your team combined.
