Here at Riot like to balance AP items
-
Nerf 75% of the AP items due to a extremely small increase of gold income in the game. (Items nerfed: Luden's Echo, Rabadon's Deathcap (a.k.a most expensive item in league), Zhonyas Deathcap (extremely huge nerf), Archangel's Staff, Rylais Crystal Scepter, Lyandry's Torment, Void Staff, Morellonomicon, Athene's Unholy Grail);
-
Buff items like Will of the Ancients for just
re-arrange Rod of Ages for HP and mana stacking champions like 
, 
, etc, buff Abyssal Scepter for close range AP agressive champions; -
Nerf an AP support item because AP champions hate the extreme gold nerfs on AP items and AP laners are abusing it;
Now since i'm a support main, I LOVE Frost Queen's Claims. But AP champions taking it feels so wrong. And riot is nerfing raw stats the wrong way. -5 AP might not hurt, but it's still -5 AP (hello warrior nerf), nerfing the spooky ghosts (the right way), nerfing the mana regen was also the right way, but it's only the right way because mana potions were removed.
But THE ONLY THING IT SHOULD AND MUST BE NERFED is the passive.
Seriously, why not disable the god damn Tribute passive when killing a minion? Why did riot removed it? It just completely defeats the purpose of an AP "support" item. Obviously the active is still strong (and I admit it's too good), but now nerfing raw stats is just bad for support champions.
The hole purpose for AP laners to buy this item was for the mana regen and extremely good active. But now, getting nerfed because solo laners buying is like Swain, Karthus and Malzahar were nerfed because "DEATHFIRE TOUCH TOO OP ON THESE CHAMPIONS PLS NERF".
Sorry for the rant. It's simply unfair for AP champions and AP support champions.
TL;DR: Currently spooky ghosts nerf is OK, but nerfing raw stats like AP is wrong. Nerfing the Tribute passive to be disabled when killing a minion is the right way to balance the item.
P.S: If the current changes for FQC and Talisman goes through, i'll start using Talisman on Sona.
, need some damage-get 
), and its stats are good. Yes, it is more expencive, but same is true for all other items. Actually, if we compare FQC to Morello-we will get:
50 AP vs 80 AP
10% cdr vs 20% cdr
100% manaregen vs 100% manaregen
Goldgain passive vs heal-reduction passive
Great active for immobile skillshot-based mages, and still good for others vs nothing
2200 gold vs 2550 gold

+ any mana regen...you get the idea. If anything supports have room for additional mana regen in 
(which again is WAY BETTER FOR THEM GIVEN THEIR BASES).
I guess my point is, the mana regen had to go, because as long as it had it there was little incentive to build other mana regen items/support items.
part of the line. At 850 gold, it grants 100% mana regen already, as well as the AP, and gold-gen. Considering how just 100% mana regen cost, at base cost, 500 gold, consuming 4 item slots, paying a little bit more to have the same regen, plus 10 AP, plus passive gold gen, just makes FQC all the more valuable as an item. Right now mages are really stressed for having mana regen, gold, and damage, and just the component for FQC does it all. The only reason you see them further upgrading it anyway is because of how much raw power the FQC active has, let alone the increased gold gen even further.
