There NEEDS to be a counter to shields in this game/Banshee's Veil rant

Dear Riot,

I love this game I really really do honestly, but seriously why do y'all leave shields in the current state they are in. I know Riot has seen the trend of bot lane supports and one of the top tier junglers being shield bots. I am not saying them in general are the reason why its aggravating to play into them because anyone of those champions when played well is always a sight to see. The problem comes from the fact shielding has no direct counter for example a problematic carry builds life steal you buy items with grievous wounds, a problematic carry hurts from AP burst you buy magic resist, same can be said for an ad carry. But what do you do when said carry gets nearly 3 health bars through shields, self healing, and burst health from redemption when they made a bad fight and should be punished for it. Absolutely nothing, you just sit there and take it. Then this scenario repeats itself until you don't even do enough damage to break the shield before a team fight ends. I'm not saying i want to see these champs shield values dragged through the dirt till they aren't even good I just want a solid way be it item buy, champion or champion ability to drastically reduce shielding or even break shields to allow a solid way to fight into shield comps.

Also while I am at it can I ask why was Banshee's Veil released in the state it was cause if i remember correctly all the mages were complaining and whining about release and buffed edge of night but then y'all just go ahead and release a better buffed AP equivalent of edge of night, I mean if this item had pen or mana/mana gen it would literally be a first buy for every single mage and without those its still a first if not second buy on nearly every mid lane mage in the game even AP supports tend to pick it up when ahead. The item offers way to much for literally every stat on it being passive.
