Hi, i do not post on the forums regularly but i have noticed alot of people with problems with Affli lock damage both ST and AoE.
This guide will be AoE only as ST has more details to get into but i regularly top damage with 250k sustained DPS(ST).
I can not speak for other specs as i have only really mained Affli since Vanilla. Anyway here is the guide, hope it helps you.
having base 3 shards now is crazy for damage, especially AoE.
Prio list:
1) 3x Unstable Affliction
2) Seed of Corruption(SoC) on that SAME target.
3) keep spamming seed of corruption until UA is going to fall off
by the time you cast each SoC, the UA damage will have burst the previous seed giving you crazy numbers, especially since now you have corruption on all targets.
Enjoy
