The tier 8 has been mined from mmo-champion here.
The 2-set bonus as of now(It could always change) increases the damage done by your Unstable Affliction and Immolate spells by 20%
So my question to you(I can't theory craft or run numbers) is does this mean we get Immolate back in the Affliction rotation again?
We lost the %5 buff from shadow's embrace and 20% from haunt, but we gain 20% back due to the bonus. We lose 10% from Molten Core but we could gain 6% back from Aftermath. Unless I'm missing something that means we lose roughly 9% of the damage from the immolate spell, but would it still be worth using? I havn't been keeping track of many of the Warlock changes but this set bonus caught my eye.
