Minor idea to rework a niche item to counter shields

Instead of penetrating shields (which would be visually confusing, tbh, to have a shield but not see it reduced as your health bar goes down), a disabling mechanic might be key.

An item like that, able to disable shields (think Sombra's ultimate from Overwatch) or severely reduce their effectiveness, would have to be balanced by small range as to not make every shield item/ability on a team useless, but heavily reward the champion who can dive an entire enemy team and activate it. Whether or not that's too easy is up to debate, but there just so happens to be an item that's underused but fits that niche perfectly...

Make glorious again. Remove the aoe slow, give it a shield reduction/deleter (but allow shield secondary effects to take effect, such as Lulu's passive, Janna's AD boost, or Riven's dash so champions can still use their abilities to partial effectiveness). If "disable" isn't cool enough of a debuff name, perhaps something like "Shattered" or the like.

Because of RG's cost, it could be both a tank support item to allow them to counter enchanters in bot lane, as well as a niche item tanks could make if they're willing to sacrifice a little MR/armor to increase their team's dps effectiveness.

This might be a shit idea, or the best idea ever. I don't know, I'm practically bronze. I just like playing Overwatch this year, and Sombra's ultimate got me thinking.
