The Big CDR Issue

As items get adjusted there is a big gap I see when itemizing a certain group of AP scaling tanks. Due to their sustain approach and reliance on abilities CDR is an absolutely key stat on them , however, unless they are being played in a support role their itemization options for getting that stat are terrible. Right now these champions are either not viable solo lane or are just picked to farm top and wait for team fights due to a serious lack of item options to duel 1v1.

In a solo lane situation the aura support items are too inefficient, while the pure AP CDR items are too glassy. What's left: Frozen Heart, Spirit Visage and Frozen Gauntlet. FG is no good they all have enough cc built in, and FH and SV, are situational, purely defensive items.

What these guys really need is basically a go to AP bruiser equivalent of Black Clever of sorts. Not necessarily this but here is an idea:

Frozen Chains Kindle Gem + Fiendish Codex + Ruby Crystal + 930g 500 Health 40 AP 20% CDR UNIQUE passive: Punishment: Your next movement impairing ability will deal an additional 5% of your maximum health magic damage to all targets hit (10 sec CD).
