Should there be a GW effect for shields? New Aatrox has it in his passive.

Seeing that Aatrox's passive now inflicts a "Grievous Wounds Plus" effect that affects both healing and shields, I have to wonder if Riot intends to add an item in the future that acts as an anti-shield GW weapon.

In the past, I've entertained the idea of an item that causes its wielder to deal bonus damage to shields, but it causes muddied calculations when used with burst attacks. Anti-shield bonus damage exists on Irelia's passive, but she can't burst with it on the level of, say, Zed.

Having an effect that causes shields to halve in effectiveness seems like a much more straightforward approach. It doesn't result in as many "How did that blow kill me?" moments because you knew (or should have known) ahead of time that your shield was weaker, meaning the onus is on the player to accommodate for their weaker shields.

On a related note, I also wonder whether Riot intends to change GW to affect both heals and shields altogether. That'd probably be a bit too much, though, as it'd make totally useless.

Any thoughts on this?
