Okay so, I modified the current combat routine for my Jade WD. I have it spamming horrify successfully(regardless of setting in Trinity), as well as casting Soul Harvest after casting out DoTs and such. It's not anywhere near perfect as I haven't a clue what I'm doing for the most part, but it's better than default.
I'm using current beta(r487) & Trinity 2.1.21. Been running bounties on T6 for an hour or so. 0 deaths.

Just extract into DemonBuddy folder. Overwrite file. The only file changed is WitchDoctorCombat.cs & the only things changed in there are in regards to Soul Harvest & Horrify. I didn't mess with anything else. Maybe backup your ../Plugins/Trinity/Combat/Abilities/WitchDoctorCombat.cs just in case
