LF pro affliction PvP/PvE lock

Hello,

I'm affliction warlock and I feel my damage su** a litte bit. I just did Toes10man and my dps was like 150k on first boss, 90k on tsulong, 75k on lei shi, and 95k on Sha. I know it's a bad dps cause I'm 510 ilvl (pvp geared).
I'm using addons like NeedToKnow, Affdots (i feel it has delay so It's hard to update buffs with this).

I'm looking for someone who can give me some tips, show me what im doing wrong.
My rotation:
Opener: Pre-pot, SB:SS, Malefic, after procs up I'm using trinkets Dark Soul etc and refresh manually (so I got full duration from pandemic from previous dots)->Haunt->filler then refresh again just before procs go off
My stats are like Haste ~21% selfbuffed, Mastery 60% , Crit 15% or something like that.

I'm fully gemmed for haste I'm condsidering to leave haste at 7073 haste beakpoint and go mastey for everything else. Maybe it will help.

Well your mastery is a bit low, but even that is not a problem. You can see report in bugtracker that agony is not benefiting form snapshot, but for me it does but not like it was. Before the update my agony would do around 600-700k dmg with procs now it's around 450k dmg max. And yes it's increased with procs, problem could be base spell dmg i dont know.
