a couple weeks ago on the PTR, I did quite a lot of testing around the reworked Holy Point Shot and the new Shadow's builds it enables, and made some guides for them. I've updated them again a little bit now. I have three builds in total depending on what you are going to do: solo pushing, group play, or torment / low GR farm. I hope you will like them!
I know that especially for groups there will be a lot of people asking how viable DH will be compared to Monk and Wiz. The short answer is: we don't know. The long answer is: Monk is probably out entirely because Wiz and DH are new and slightly stronger, and between Wiz and DH there are some differences in how they are played and how strong they are for killing the RG, but overall they will most likely end up at the exact same level.
As for the torment / low GR build, I think especially when farming in groups, this has more potential that UE Multishot, so it's a top notch farming build. And the solo build, it's a little bit behind the other top builds we have on DH, but still top 10 viable.
