Mordekaiser's Passive is giving an incomplete picture of his dmg taken in postgame [GAMEPLAY/CLIENT]

TL;DR: Mordekaiser's Passive is messing with his damage taken stat in postgame stats, because you have to be damaged on your healthbar for it to count, even if you tank 100k dmg, if 80% of that is stopped by Iron Man, the stats show 20k. Unless Riot ONLY wants damage that actually sticks to be an indication of how much tanking someone did, this needs to be differentiated, and not just for Mordekaiser, for invuln-y/untarget-y mechanics like on Taric/Kayle/Kindred as well.

Played a game, lost lane against a HARD ( I went 1/5 in lane but caught up and stayed neutral midgame. He DC'd midway through midgame and we won the 50 minute 4v5 game in the end due to dragonforce being OPAF with elderdragon and a tank-onhit Juggerkaiser build. Their AP mid, 2/9/2 , and our lategame comp kinda countering theirs TOTALLY had nothing to do with it). I was our teams forefront tank with our being our secondary tank and primary diver, but I was shocked to find that I took the least damage out of anyone, even less than our 5/4/10 when I went 9/9/14. With 23.5k damage taken, I was only beaten by in least damage taken, with 11k dmg taken because he afk'd/DC'd at the 25 minute mark or so.

Long story short, I'm pretty sure 's Iron Man Passive is skewing his damage taken stat, since incoming damage (excluding true/pure dmg, ofc) is first COMPLETELY negated by his passive's shield depleting, BEFORE being actually dealt as damage to him, so it doesn't even register as taken, even though the damage is sunk into mordekaiser and doesn't go anywhere else.

This isn't a GLITCH per SE, but it certainly is something that probably wasn't intended, as I'm pretty sure how much damage negated by his passive doesn't even factor into mastery grades or any other stat besides damage taken, and it could certainly be improved into something that provides a more complete picture. As far as I know, shields and spellshields actually tally the damage they absorb into "Damage taken" as well, so if that's the case the interaction certainly is unfair towards old Metalman. It may have something to do with it actually being part of the healthbar coding, IDK.

However, there are possible solutions. For example, an "incoming damage recieved" stat that tracks how much raw damage 'hits' a champion before being reduced/negated by armor/MR, invulns, untargets, and post-damage mitigation mechanics (this last one would be difficult to implement because it probably messes with healing done as well) is a much more accurate representation of how much heat you're taking that may or may not 'stick', as opposed to "damage taken" which indicates that the damage DID stick.

I don't even care if it's a simple-in game tooltip that tracks how much damage 's shield has absorbed, the stats are incomplete because of the interaction, and I would like to be able to see how much damage I ACTUALLY tanked.
