I suppose it depends, there is no way to exactly transform from utility like cdr to an observable effect. Unlike AD/AP/penetration when enemies are just melting if that stat is high enough.

Look at Evelynn, she has 1,5s cd on q, and cdr won't give her much. Similar to other champions, if you are close to low cd (2-3 s) it's difficult to spam abilities like that, they have animations and additional things.

I suppose it's a matter I discussed partially in paragraph about caps.

There are many variables to follow, but in terms of theorycrafting cdr is just special. I wanted to point out that thing, not exactly recommend something. Even if I did, there is wide margin of tests, which are to be performed by every player separately.
