Should shielding supports be less effective at self shielding?
I constantly see the argument that shielding supports are squishy but that's only if your actually damaging them without their shielding and CC. Their itemization even come with defense stats so while they aren't as durable as tank support, they can definitely become on par with bruisers.
One of the future changes I hope to see is having shielding by supports remain the same or stronger on allies but weaker on themselves. They should be rewarded for enhancing and peeling for allies but realistically risk being focused/targeted themselves without having access to the same giant shield that is meant for teammates.
