I have an LR CC+PS CC workflow, and I have never been satisfied with RAF sharpening with LR or ACR. With both my X-E2 (v.4.0) and X-T2 (v2.01) the "wormy" artifacts are ever present. I have tried many of the suggested/recommended options, but I find that my LR+PS habit is hard to break. However, I have found a solution which works quite well for me.
I use Alienskin ExposureX2 and On1 Photo RAW 2017 as LR/PS plugins and external editors. On importing RAF files to LR I have LR Sharpening set to 0 rather than the LR default.
I make all other LR adjustments including crop/straightening, excluding any sharpening.
Then depending on what I plan to do with the image I will edit in either Exposure X2, or On1 Photo RAW 2017, either of which I use to apply sharpening if needed. The finalized rendition of those edited files are saved back to Lightroom, and there is no evidence of the "LR RAF worms" or foliage waxiness.
Occasionally I will bypass LR and use either Exposure X2, or On1 Photo RAW as a standalone with results I am happy with. My big hope for this year is that Adobe will get their act together and fix this RAF rendering issue especially with regard to sharpening.
