Taking aside shadowlands borrowed powers… too simple, not fun talents, most of the talents are static (dmg x, y, z), no strong synergy between talents, lack of complex passives to build power up during the combat…
Duration of Agony and Corruption should be longer from M+ perspective as baseline +10 sec each, now we are good cause there is agony conduit.
Rapture is bad in PvP, makes the UA → Fear breaking faster. Could be removed.
Row 1
Nigthlfall stack 2 times, but reworked after Drain Soul baseline.
Drain Life idea is ok.
Drain Soul baseline and new pet sacrifice talent in this row.
Row 2
Agony not bad but ramp up time should be same = 20 sec not 28 sec with 0% of Haste.
Corruption is boring as a spell in general, low dmg and no interactions. Maybe 30% slow effect baseline? It match to the name. Corruption talent is boring, it could increase slow up to 50% and make something additional.
Siphon Life to removed, make UA talent. It’s DOT row and UA have no any talent.
Row 3
Burning Rush to be removed, make talent for our 2 min def cooldown.
Fix mobility, make Demonic Circle work like instant Doors of Shadow.
Row 4
Total mess row.
Seed not best but only working in strong aoe. Seed should detonate Seed.
Phantom to be removed. New talent needed. Maybe UA cap up to 3 targets.
Vile Taint maybe apply also Agony? Slow part not needed.
Row 5
Darkfury also instant.
Mortal Coil is ok.
Aoe fear only used in pvp. Baseline talents are pve. Replace with Fear talent, feared target will not be running around and not enter combat.
Row 6
All is trash.
This is almost final row, the feeling of power need to be in those talents. All to be reworked.
Row 7
Last row also to be reworked.
Soul Conduit - move to row 6,
Creeping Death - move to row 6,
Dark Soul - Integrating with Darkglare will make it strong cd.
New last row talents?
Corrupting Leer is not bad to be a last row talent in case of AoE, bursty talent.
Wrath of Corruption is not bad to be last talent also, maintaining buff style.
Last can be Malefic Wrath for ST but time should be xtended.
