Blizzard killed the end game viability of the Thorns Minions build this season thanks to the entire rework of the gear stats and difficulty levels. While it was always at best a C Tier build, it was good enough in Seasons 4 and 5 to do all the end game content.
However things drastically changed with the massive rework to the game this season. Thorns in general got weaker from the stat squish. Thorns don’t scale as well after this change as they did previously. That’s why you don’t see the Thorns Barb or Thorns Spiritborn doing well as other builds in their respective classes.
The Thorns Necromancer always was the weaker sibling to other classes Thorns builds as bugs and oversights have held this build back including % Summoning Damage not working on Thorns as well the Needleflare Aspect never working on Minions even though Blizzard stated they fixed it in Season 4.
So given all that was holding Thorns back on a Necromancer build, it got exponentially worse in Season 6. Blizzard knows that the Thorns Necromancer is vastly underperforming so they implemented a last minute change giving the Bone Golem an increase from 70% of your Total Armor converted into Thorns when the Golem is activated to a whopping 200% of your Total Armor converted into Thorns.
On the surface this sounds great. Thorns is finally a viable option for the Necromancer. However this change actually made the build even worse in the end game. You start to feel your damage nerfed once you get to Torment 1 as you lose 250 Armor. It gets progressively worse as you increase your Torment difficulty. By the time you get to Torment 4, you’ve lost cumulatively 2,500 Total Armor or 7,500 Thorns from your Bone Golem just from changing your difficulty levels. No other build gets this large of a damage nerf just from changing your difficulty levels.
To try to overcome these built in damage nerfs, you need to stack + Armor and % Total Armor on all your gear and tempers. That means you need to make a 100% commitment to a Thorns build and forgo every other type of damage. Your Thorns build at the end will need to have 20k Total Armor just to do enough damage in Torment 4. Even then only your Bone Golem will be doing all your Thorns damage. Your Skeletal Warriors will be doing little Thorns damage where in previous seasons, it was actually possible to make them your primary Thorns damage dealer.
So the other large problem still exists with this build. How do you do damage to passive targets that don’t proc your Thorns? This season the answer is the reworked Mendeln Ring. However because your build is 100% committed to getting as much Armor as is possible, you don’t have anything left to buff your Mendeln damage. Even without any buffs to CHC and CHD, the Ring of Mendeln will actually out damage your Bone Golem’s Thorns in most circumstances.
This tells you the sad state Thorns is in currently. Even after making a total commitment to putting in as much Armor into your build as possible, you’ll still do more damage from one ring that you’ve put zero effort into supporting.
Unfortunately I’m forced to make a decision now on how I what I want to play for the rest of this season. I can continue with my favorite build in the game and be frustrated at being stuck in the D Tier this season and struggle to play all the end game content, or I can accept the fact that Thorns just isn’t viable after all the changes made to the game, and go all in on making an S Tier build revolving around a certain ring even though it’s not my preference in how I want to play this game.
