As we already know when you finish a game and view that stats, you see Damage Taken. However Damage Taken does not necessarily mean how tanky/beefy you were for your team. So can add damage mitigation to the list to be able to see how much damage we blocked?
Edit: Ignore that title.
Edit#2: CrimsonCobra3 pointed out another great feature to add in the stats: a CC Tally
> I'd also like a CC tally. (Number of times you've CC'd an enemy champion), and split self-healing and ally-healing.
