There was! Did you read the part about "the difference between favoring crit and mastery is so minute overall"? And more importantly: Did you test it?
Here's a better (yet longer) one for you, where people who actually know what they're talking about explain in detail why and how stats affected your spells in 5.4:

You can also look for Twintop and Drye's interview in Finalboss where they briefly explained how things worked in 5.4 too.
As for FDCL, as you yourself have repeatedly pointed out (and which was my point from the beginning), MFI is not better for protectors because:
1. The bulk of your damage will come from DoT management (and most of your time will be alloted to it)
2. When you actually do cast a filler, you'll likely use mind sear if adds are stacked
3. When you're not managing your DoTs or casting Mind Blast/t90/Mind Sear, i.e. when you're casting your lowest priority filler, you should switch back to 1 and 2 immediately, forcing you to stop MFI, which will result in overall suboptimal MFI usage; while FDCL (or even mindbender) allow for optimal use of your lowest priority filler. Which is ultimately a moot point because of 1.
It's not about making FDCL "a thing". It's about debunking the popular myth of MFI being
vastly superior on
every situation because noxxic told you so. Which it's not.
And yes, Imb4 "discussing 5.4 with WoD at the door". I know.
