I appreciate the response. Very well stated, and that makes sense, to the degree that I understand how Mr Robot works.
Basically, here’s the final rundown of what I’m seeing after doing a boatload of research and studying top world resto gear and talent choices:
Current BiB results: Truly is BiS with those combinations as long as I run germination (primarily) and cenarion ward (which I typically run by default; germination, for raiding, I don’t normally) as talents and equip aman’thuls wisdom (shoulders). Those shoulders are the key to BiB results.
Current BiS results: Truly is BiS if I choose not to run germination, unequip the shoulders, and equip the dark titans belt for boosted lifebloom performance.
This is actually a really cool outcome that I wasn’t expecting from Mr. Robot. Based on a few extra simulations I’ve run for ToS, the BiB and BiS differences are practically giving me two different play-styles that will both perform to near par and depends ultimately on how a I want to play my resto druid: Spring blossoms or germination (ultimately). That’s quite impressive. I raided some mythic Goroth last night with my guild, ran both gear sets throughout the night, and, even with the BiB items lowering my ilvl from 930 to 924 over BiS, there was practically no difference in my healing (actually, the BiB might have been a tad higher, and probably would have been more so if I had more play time with germination for raids and how to execute it efficiently).
So, I believe Mr. Robot’s “discrepancies” here aren’t discrepancies at all. It’s offering two different ways to play with two different choices for talents that are practically identical.
