If riot wants supports to have such broken items, then they need to cost more gold.
Around every support item in the game atm is pretty much close to being 1k gold undercosted.
They can have the late game, but it should atleast cost them something, ardent shouldnt cost less than 3k gold, neither should locket or knights vow or redemption, THEY SHOULD ACTUALLY PAY for the BROKEN passives/actives, not get them for free, you know just like you have to spend almost 3k gold on the shit stats for the zonhya active.

top after lvl6 (unless they did a fix to his clone procc'ing it))
is mainly good if paired with other shield powering items
is only as good as the person you're linking to dps and
yes it does have a good amount of burst shield but it decays in a 2.5 second duration so if you disengage when it pops like
ult it becomes pretty useless
