So this was actually the first build I was able to get "going" when S3 went live due to some very weird luck with my RNG. My hexing pants were abysmal (ty smartloot for giving me an int pair with armor and life regen), but I was able to make one little change to make this build completely faceroll in T6: Goldwrap. This belt, when combined with avarice band + boon of the hoarder, makes you damn near invincible... if you can keep the buff up. In dense rifts you don't need to try at all, but if you encounter sparse rifts and your toughness is naturally low, you have to be very careful.
In order to keep my hatred up, I had to roll hatred per sec on my offhand (a K'mar Tenclip until I can get a calamity) and my chest. Additionally, I had to use hexing pants (when the buff is active, it improves hatred/s effects including the archery bonus for offhand hand crossbows). While I'm not quite hatred neutral, I'm damn near close.
