Speaking for M+ Disc: changes look pretty bad and ill-conceived. We are going to feel the loss of Aberrus set very hard, and new set does not compensate in even the slightest regard. Insta-proc Radiance was the only way to deal with the group-burst high mobility combos that were so frequent in S2, and I suspect will become a pain point in S3 as well.
The 4-set is tied to Shadow Cov, and that’s now tied to Mindbender/etc, a long CD. I don’t see this set having the same impact as insta-proc Radiances. Furthermore- it’s just more dps, and if Atonement isn’t in a healthy place (it’s not in raids, and barely acceptable in M+ with the S2 4-set) it won’t be a worthy healing tool.
Harsh Discipline was a personal favorite and I enjoyed the determinant nature of it. It’s what a good rotational passive talent should aspire to be. Changing it to RNG already sounds bad and unreliable, but to attach it to the now nerfed, casted Radiance is going to limit it from being useful in situations where you want it.
Mind Blast is now just Schism by another name. Not useful, not cool. Plays havoc on Twilight Equilibrium. They’ve removed so many of the options for proccing TE, which hurts those who like the complex rotation, but then also disrupted the simplified rotation I prefer (MB->Smite->MB->Smite->Penance). Everyone suffers for this.
Luminous Barrier wasn’t seeing play, so they decide to nerf PW:B instead- not cool. PW:B already has constrictions to justify that meaty damage reduction, nerf the reduction and keep the positioning and timing requirements and you get another non-impactful wet-tissue-feeling group CD.
With the Mass Dispel changes, they had better remove Bursting. And the all-around utility nerfs seem so misaimed- trying to undermine Exodia shadow priests, but the end-around hurts Disc and Holy more, who needed the utility just to keep up with others’ special toys. Reminder, Holy Pallies still have an Invincibility button and Battle Res.
And the things they left untouched or unaddressed:
Aegis of Wrath untouched. Contrition still weak. Train of Thought, weak. The class tree still wracked with throughput vs needed utility binds. Shadow-Atonement half of the tree looks more mandatory than ever. PoM and Renew still lacking any synergies anywhere for us.
I know I had conflicts with the group of Discs who enjoyed the Schism-tree branch, wanted the complex Atonement-focused rotation and so on- I don’t like that style, but I still didn’t wish these kinds of radical changes on them.
