Primal Wrath & Brutal Slash are well balanced talents on their row and I think you should consider giving PW the 20% treatment as well. Unless its a heavy or consistent AOE fight (Prototype, Vigilant - and even then many take BrS for the later), we often always take Brutal Slash anyway so if anything PW needs to be equalized in buffs. Therefore I think you risk upsetting balanced talent choices here (you could also consider buffing Rip by 10% along with the 10% to PW). 20% Brutal Slash is great though and should make it feel satisfying to use. edit: technically Swipe buffs are also PW buffs, but would still like to see Rip buffed too.
Lunar Inspiration is sadly missed out, which I think easily could have received a 15%+. A very fun talent, and just because Necro’s use it in PVP doesn’t mean it should be overlooked; a lot of its value there is its ability to generate cheap ranged CP’s while being kited etc, not entirely for its dmg, so a buff won’t upset things. This would also help Necrolord in PVE. Don’t forget this spell doesn’t scale with Mastery and now late in the xpac, its at its weakest point - nor is it amped up by things like Frenzyband (doesn’t apply from DOT ticks).
edit: LI also loses value as Swipe gains more.
Feral Frenzy would have also liked to see a small buff - again, its value in PVE is lower, as the burst CP generation is mostly valuable for killing players and not bosses. The Swipe etc buffs will help MOC a lot, and BT is already good, so Feral Frenzy falls further behind on the final row. Also once again, this would also help other covenants as its nice for Kyrian and Necro, synergizing with both covenants.
Pred/SR/MOC talents all benefit well from these buffs. Just would like to see LI + FF as well.
I think these changes risk hard locking us into Frenzyband though. Circle already fell behind when 2pc was buffed (another reason to consider a buff to Rip as well as previously noted). Apex will probably still be solid, but slightly more 4pc buffs could certainly secure its viability as a 2nd AOE option, as Swipe buffs are big for Frenzyband (and Apex gives very fast CDR for 4pc, hence 4pc buffs can ensure it remains a good option).
Overall, good changes, a few under performing talents/builds still deserve a look at though.
