Can we get some skill-based tank busting support items/spells?

There's so many spells and items in the game that either make one's own team tankier (redemption, stoneplate, locket) or temporarily disable burst champions (exhaust, thornmail, kindred ult, zhonyas, arch staff) but none that create temporary windows that the team can deal % health damage to a single enemy or group of enemies.

I know the boards have a boner for tanks but there's many times in champ select no one is playing a tank against a team of 2 tanks. What's the counterplay for lategame? You're just supposed to dodge?

I'm not saying the item should be strong enough that you can disregard team comps entirely, but there doesn't seem to be many build options to at least create chances in these scenarios for skillful outplays. There's BORK, that's it.

Maybe an item like Redemption but instead of healing after the charge-up time, it makes all the enemies in the radius take an additional 3% max health damage from all attacks while they remain in the radius. Maybe someone can come up with something better but I'd just like more options for this kind of thing. Things that create WINDOWS of opportunity in these scenarios, not hard counter the entire tank class. Follow me?
