Balance: A shield buster item?
To shake things up. How many times have you raged over a Janna/Lulu/Orianna/Lux/Shen/Lee Sin/Riven etc shield totally denying your burst either by a quick reaction or just good timing?
Could be an item similar to the healing debuff that is nearing removal from the game. I'm a fan of building around team inequalities vs "losing at champ select."
Proposed: Attacks and skills that would damage a player remove 33% of shielded damage on hit. (Or perhaps it could scale over time from 0 to 100% sort of like a slower statik shiv.)
