Post-game "Damage Mitigated/Shielded" Stat

I love looking at the stats after a game. It gives me an idea of how I did compared to other players. When I play support, I love to see how much I healed compared to damage taken, but I don't always have heals as a support. Therefore, I suggest a new stat: damage shielded. If I play or , I want to know how much damage I actually saved from affecting my team. It could also be extended to armor/mr buffs like 's W or 's W aura.
