New Mastery on Morde

So, the new mastery gives a shield that will probably be based on your health whenever you inflict cc. Since we do not know if soft cc like slows apply, we can assume it's probably going to apply slows too. So, what if a morde builds a rylai's (if it's still going to be good on him) with this mastery? It seems like this might end up becoming a strong one that's for sure.
