[Suggestion] Shield breaker + damage prevented data

Given the prominence of player shields nowadays, and the ability to deal with other types of things in-game, it would be nice to have an item (or maybe more champions with the ability) to counteract shields in-game. Could be shield piercing or maybe a CD'd dispel (a la DotA purge.

It would also be nice to have a "damage prevented" stat in post-game to see how much damage was prevented by shields and the like (e.g. Phantom Dancer and Bond of Stone).
