I wonder if it stacks multiplicatively? So it's either 65% or 54.4% which puts Zz'Rot on a 42 or 65.28 second cooldown ... great idea. Now I wanna test it out, but on which champion? Gangplank Inspiration/Domination ... get stacks with your ult and gold with Kleptmancy. Zz'Rot, Sightstone, Trinty, Sterak's, split push all day?
I have proven that it reduced my Titanic Hydra to 8 seconds, from 20. 8/20 is 0.4, so that was 60% cooldown reduction. It's definitely additive. I watched when I clicked my Hydra and the countdown started at 8 seconds. So it's additive. I did not have the 5% at that time because I was running Prec/Dom.
I think the 5% might not be that important, so you may not need to take Inspiration. Both are in secondary trees so you can mess with however you want to set up.
I'd do either an insp/dom or res/dom on Shen or Galio top. Shen is probably better, because don't forget you do need to get the bounty stacks, and those come from other lanes. You could ult bot and get a +3 potentially. Galio can also do this but to a lesser extent. The champ definitely has to be a tank or bruiser because zzrot scales off hp. Overall, I feel Shen is the best candidate for this, but any other tank who has tp can also do it. The downside is, you will be buying a Ruby sightstone, which is not exactly a good stat item.
