Shields are too frustrating

I know people probably won't agree with this being an item but I've been constantly feeling lately that just like how we can reduce healing to anyone that grevious wounds should affect shields as well, because there are many shields in the game and they are on very low cooldowns. It's never fun when the enemy adc is doing poorly and the only reason they are staying in the game is because they have a Karma, oriana and Ivern all on one team.

The adc won't have to buy any lifesteal seeing that the support can build ardent censer which gives lifesteal and increases shield and healing done. then karma will just ult shield or normal shield on a fairly low cooldown, and an Ivern which can also shield which does damage and he will build Holy grail increasing that shield strength, two of the champs listed there use Windspeakers making those spells even strong from there, so the ADC is constantly gaining protection.

Now i've been saying adc as my example but these shields could be casted on anyone else. essentially all supports gain full cdr and have an item that will increase heals or shields. I think it'd be pretty fair if there was something to actually fight back against shields just like heals it doesn't have to be as strong but something makes a difference. Especially cause these champs which are very popular are strong for a while now. .

I'd like some opinions on this. I've also done small math on this base shielding from these champs with at least 3 of any of them come up to 600+ with bases alone.
