Shielded Damage Stat

There should be a stat post-game with the amount of damage shielded. There was a lot of talk in the pre-season about how to make support feel more rewarding, etc. There's a stat about how much healing done, but not about shields. I think this would be a cool stat to view as Janna, Lulu, Thresh, etc. It should include shields from abilities as well as active items.
