Warlock BiS, Patch by Patch - Finalized

No world bosses!! (keeping it a little realistic)
The below is the Bis of the Bis, universally accepted, diligently theory-crafted, Xashe approved.
With the release of BWL, and some +spell hit gear, we finally have a sturdy base to build on. I've started a list of the primo BiS from now till the end of vanilla, broken up into the upcoming patches.

Patch 1.10 (non-content) changes:
-Nothing, cry more noobs.
Patch 1.11 (Naxx - non-Frost Wing loot) changes:
Helm - XXX -> Plagueheart Circlet - Quest

The 2/8 set bonus (Your Shadow Bolts now have a chance to heal you for 270 to 331) is always reached since Tier 3 head, chest and boots are best in slot items. The 4/8 bonus (Increases damage caused by your Corruption by 12%) is very easily reachable with Plagueheart Shoulderpads, meaning that the set bonus worth discussing is the 6/8 bonus (Your spell critical hits generate 25% less threat. In addition, Corruption, Immolate, Curse of Agony, and Siphon Life generate 25% less threat), extremely handy in threat-sensitive fights.
The 6/8 T3 set bonus is most effectively reached by adopting the Plagueheart Belt and Plagueheart Gloves over your Eyestalk Waist Cord and Dark Storm Gauntlets.
