New support item idea

so i am a support main and i play alot of squishier supports like and i always have this problem when building armour items, like frozen heart is a good support item but i feel like it is too big of a purchase for what you get out of it, what i think we need is a support tri force(hear me out here) we need an item like locket that gives armour health and MR and an active effect that can give half of the stats from that item temporarily to one of your team mates, let me explain, locket is a aura MR item with an active shield, we need an active that gives off an aura of armour and mr, so like locket but instead of a piss weak shield that blocks like 50hp, we need a defensive buff because as a support i feel useless when my ad carry gets melted by say a or a ult, if i could use an item to give them enough resistance to get out with 200 hp then that is better than them just dying outright, keep in mind you would need to manage when you use this because it would most likely have a long cooldown, another idea is the same thing but like a ward, so an item that is a shrine that gives your team defensive properties, please give me your feedback on these ideas, and please, for the love of league, no trolls, if you disagree then you are entitled to state your opinion but do not try to put me down or tell me im a noob, ik im a noob and don't need to be told.
