Shroud of the Lightless - 45 sec cooldown?

I've been trying to figure out this chest and I think that perhaps this is the chest Wild Strike has been waiting for, but that Shade Form appears to be completely useless with its 45 second cooldown. There was a reddit post a few years ago begging for either a cooldown reduction support or suggestions for storing charges on cooldown skills. Until something like that is in the game the skill on the chest is pretty fucking useless which is a disappointment considering how rare it is and how good the spell is. Shit needs to have only like a 10 cooldown or maybe 30 sec cooldown but 100% chance to cast the spell. Otherwise you will trigger it maybe twice/map?

I don't know what the best balance would be there but at 45 seconds I would use an Annulment Orb on that mod if I could. It's just taking up space. The flavor text says "look to the darkness" and well you're only in darkness for 3 seconds every 45 seconds so you're pretty much guaranteed to 'go hungry' - unless you use Immortal Call which requires little investment, more reliable, and no darkness travel necessary.

By the way these Abyss uniques are totally GGG's take on d2/d3 set items - without being explicitly green or having specific set bonuses or something. Not only do they have thematic synergy but mechanic synergy together unlike anything else I've see in the game. This has to be the first real PoE item set done in a way that works for GGG.
