He is not saying it is new. He is pointing out the fact that a lot recent reworks and champ releases have some sort of %dmg. Nida has both, Mao has one, then there is Gnar...

A thing which was somehting tied to specific champions now is pretty common, and is even expected to be incorporated into new kits. Lets say that in 2015 about 20 champs(new ones and reworked old champs) will have sth like yasuo wall/Braum shield. Interesting? not rly.
