Most likely. Every patch that has occurred after a class had a build in non-season clear GR 147 or above has been nerfed (thorns necro 147, wizards 148, crusaders 150).
The point still stands that crusaders with nerfs in patch 2.6.7a and 2.6.8 still clear GR 150. Crusaders and witch doctors have been far more tacit in their approach. Witch doctors were buffed substantially so that top players clear GR 150 (the numbers on the PTR are irrelevant as this is not the live game).
I suspect that the new DH set will be in the 144-150 range in terms of top end power. Since Blizzard decides power, it can be anywhere in that range and it does not matter what anyone says.
I think the fact that Blizzard initially held firm about the complete removal of the rend damage modifier in patch 2.6.7 after a 1500+ post thread illustrates this. If it were not for crusaders being completely OP in patch 2.6.7, barbarians would not have gotten lamentation with a 100%-150% rend damage modifier in patch 2.6.7a along with the crusader nerf.
Edit:
True. I am glad that I did not say that. You missed the point. Blizzard considers forum feedback; however, they have the ultimate power to decide. The change to lamentation relative to the PTR was identified on November 1 at Blizzcon was posted on the forums. Over November 1 and 2, more than 10 threads were created on the rend topic. On November 2, Free stated that he was contacting Nevalistis directly.
Overall, more than 30 threads were created on this topic. On November 3, the “Do Not Nerf Rend” thread was started. After more than 1700 posts in this particular thread, Nevalistis on November 11 responded that the rend damage modifier was not going to be on the lamentation belt in patch 2.6.7. This is what occurred. Additional threads were made to advocate for the damage modifier return.
After Nevalistis’s response and the “temporary” locking (that oddly kept resetting daily for a month) of the “Do Not Nerf Thread” thread, a multitude of other threads were made. Of note, one thread that was created November 12 was titled: “A BARB RESPONSE TO THE LAMENTATION NERF”. Free wrote in his OP:
This is not disputed. Therefore, one can not claim that Blizzard listened and ACTED based on you or the barb community in relation to this issue for patch 2.6.7. You can accurately claim that Blizzard did listen in patch 2.6.7a; however, they did not give back the full 150%-200% modifier but 100%-150%. Therefore, you can not claim that they listened completely.
My point stands that other classes (crusaders and witch doctors) have gotten buffs that have far exceeded barbarians and have used a more tacit approach. The idea that DH and necromancers will only get significant by following the barabarian centralized example is a logical fallacy.
