Damage Prevented Statistic

As a Karma support main, I think it would be super beneficial to include an additional statistic alongside "Healing Done" --that is, Damage Prevented. This could be something that accounts for things like shields/Barrier. But it could also include damage-cancelling items and abilities such as Banshee's Veil, Spell Shield, etc.

Granted some might argue that simply armor and MR are "damage prevented" or at least mitigated.

But I think at least a statistic for shields would be beneficial so the shielding supports aren't so left out <3

Thoughts?
