Googling for "rune of re-origination proccchance" and taking the first link takes you to wowhead where I read this in the comments:
(What I want to say is: be a bit more autonomous, like 2/3 threads could be solved by googling for 3min)
So the normal one does procc ~20% more often, but even without that, it's an imba trinket, and as WW you should take it.
Due to the huge dropptables in ToT, not getting RoR in 4 kills is the normal case... Consider yourself lucky having gotten the lfr version in the first run...
