I certainly agree that the Frost Queen's Claim route is a little underwhelming at the moment. Your suggestion is an interesting one, but I don't think it would wind up terribly impactful given that supports tend to stay with their ADCs, who obviously deal primarily physical damage rather than magic damage (unless they're Kog'Maw or, to some extent, Corki). I don't disagree that FQC probably needs some change to give it more impact in comparison with its cousins, but I'm not sure this is the best change for it. Some sort of defences debuff, akin to what you suggested but benefiting physical damage, might be feasible, and would fit in with its theme of being an aggressive support item; alternatively, an attack speed slow in addition to the movement speed slow (possibly a little weaker than current, as you suggest) would definitely make it attractive on bot lane, and would also fit in with the item's icy theme. Also, I don't see any reason why the damage shouldn't have an AP scaling, even if it's a small one. But maybe that'd be too much on top of the other changes, I don't know.

The other change I'd make would be to buff the mana regen, as you allude to. I realize that the ToA route is meant to be the 'sustainy' route, as well as the spiritual successor to PhiloStone (and Shurelya's, but that's not so relevant here), but it does seem a little ridiculous that the GP10 item path that encourages you to play a passive farm lane grants less mana regen than the one that encourages you to run an aggressive poke/zone lane. So I'd make the blues' mana regen at least equal to the yellows', if not more. This would make the lower two items more attractive, since I think that's partly why they're not picked up frequently atm (despite theoretically giving the best GP10 of any of the three routes, at least during laning phase).
