ahaha, I thought this one for hireling because I see you're using 3 crystal affix Luck and 3 crystal affix Gold Find for capping them, since bonus from Difficulty doesn't affect (or display bug?) those stats for hireling.
I didn't notice Crystalline and Mythical set affix before
BTW don't you think it's a a bit overkill using all crystal affix for Luck and Gold Find ? Since we can still obtain those from Difficulty, Nature and Hero Point Fortune (if you prefer though )
Basically it's the same setup that I use for my hireling, except the Harmony part, nice idea
Oh and I'm using Cyclone for sucking all enemies closer
thank you for sharing
