If you're getting rid of Frost Queen's Claim, bring back twin shadows.
That passive is honestly really valuable and shouldn't be discarded just because you're reworking support items. It has a lot of skill of expression and tactical thinking involved other than Face of the mountain (which, oddly enough, is the acronym FoTM, as in, flavor of the month) and tailsman which are basically just "BE NEAR ME IF YOU WANT FREE STATS!!!1!1!1!1!"
Remember back in season 5 before you turned this game upside down in 5.22? When we had twin shadows? BRING THAT BACK
