Here you go, an explanation a few posts down:

"it was a support item that benefited mage laning partners the most... but mages want a solo lane because they benefit from experience more than any other champ type, so why do we have an item that supports mages?

In addition, the CDR aura isn't as versatile as an AD/AP/Def stat aura. Example: an ally jungler pops into lane with aegis, making his gank safer for you to go all in. The aura makes every single attack the enemy throws at you less effective. Meanwhile, same scenario with Shroud and what does the item do? Basically nothing. Your carry's five second long cooldown poke is now 4.5 seconds.

This isn't to say that CDR is a bad stat, but it's not a good stat for an aura. It's an excellent long term stat, ie permanent increases with items, or boosts that last the course of several minutes like Blue or blue elixir.

In order for the CDR aura to make an impact as an aura, it'd need high values... making it overpowered for the item bearer who possessed these values permanently."
