Lets compare the talents in PvE affli build
Eradication - Nerf/boost?
When you deal damage with Corruption, you have a 2/4/6% chance to gain the Eradication effect. The Eradication effect increases the critical strike chance of your Shadow Bolt spell by 30%. Each critical strike reduces the critical strike bonus by 10%. Lasts 30 sec.
vs
Your Corruption ticks have a 10% chance to increase your spell casting speed by 20% for 12 sec. This effect cannot occur more often than once every 30 sec.
Proc chance too low, and the boost realy doesnt seems too good for me
New Siphon Life - Nerf
The Siphon Life spell has been removed. Siphon Life now causes your Corruption spell to instantly heal you for 40% of the damage done.
vs.
Dot
We need to use filler instead. If it will not leave debuff on boss - weaker soul drain ticks
Haunt and SE change for Immolate- Nerf
Who will ever use it? We need to use filler spell instead
Pandemic - Nerf
grants your Corruption and Unstable Affliction the capability to critically hit.
vs.
Each time you deal damage with Corruption or Unstable Affliction, you have a chance equal to your spell critical strike chance to deal 100% additional damage.
13 percent crit in raid are debuffs. This crit is not counted now for pandemic. So it will have higher chance to proc... But crits have only 1,5x dmg.
Improved Shadow Bolt Nerf/Boost?
Now increases the damage done by your Shadow Bolt spell by 1/2/3/4/5%, and causes your target to be vulnerable to spell damage, increasing spell critical strike chance against that target by 1/2/3/4/5%. Effect lasts 30 sec.
vs.
Your Shadow Bolt critical strikes increase Shadow damage dealt by 10% until 4 non-periodic damage sources are applied. Effect lasts a maximum of 12 sec.
Atm we had 35 percent to crit with SB so the debuff was there almost always, and this effect was there for haunt too. Now its only for SB and only 5 percent. I know, new ISB will bring raid utility, but not boost for our DPS. And fire destro will need to SB in 10man raids. Nerf for me.
I see only one boost and thats -
Suppression: Now increases spell hit for all of your spells.
Correct me if im wrong anywhere but i think we will fall down too much in DPS

. Thats a lot of love for warlock which was announced
