I've wrapped up the 4th chapter of the season now, so I've got all 6 pieces of the free set. The 6 piece bonus gives a very large bonus to Multi-shot (which I've already been using) and Vengeance based on how much Discipline you currently have. I also came across a crossbow that reduces the cooldown on Vengeance by a whole lot, so I threw that in the Kanai Cube and replaced the Rapid Fire buff I had been using. Rapid Fire didn't seem to be scaling very well in any case, and I was already mostly using Evading Shot and Multi-shot as my main damaging abilities in any case.

With just that boost from my set and those couple of new legendaries my damage output went up by more than a factor of 10. I went from running at Torment IV straight to Torment VIII without stopping in between, and I might have been able to go to IX and still be okay. Now it's time to get down to the business of running more Greater Rifts to level my legendary gems and continuing on through the next stage of the journey.
