You didn’t include a link to the AMR sims you ran @swatto86, hopefully you chose ranged target dummy as that’s the closest match to what SimC uses.
In the sim result you listed I noticed Symbiotic Presence Uptime 90% which seems incredibly optimistic to me and I’m having trouble finding a log with a hunter using it.
I’ve got no idea why people keep using Patchwerk given nothing is like that fight any more, at least as a BM hunter you can probably treat Shad as almost like that, assuming you don’t need to turtle and can keep using your abilities while doing the movement.
