I've searched through pages and pages of google looking for the answer to this question.
What I know:
Paladins have ~0.64 Procs per minute on our Jina-Kang, Kindness of Chi-ji, but RPPM effects from previous patches offer a multiplier on this proc rate if your time-since-last-proc is high. AKA "Unlucky Streak Prevention" (jade spirit enchant, legendary meta gem, etc)
Blue explanation of Unlucky Streak Prevention: http://eu.battle.net/wow/en/forum/topic/6892090046
Why I think the legendary cloak doesn't offer Unlucky Streak Prevention:
I downloaded an addon that tracks procs (ExtraCD) and RPPM effects. Based on the addon's behavior, it looks like the legendary cloak does not have Unlucky Streak Prevention. The addon very well could be inaccurate.
But why?
If the healer legendary cloak doesn't have Unlucky Streak Prevention, why is this the case? Why do (all) other healer effects offer it but this does not? I would just like some solid confirmation on this topic. if you know any good information pls share ty
