Let me start this post off by saying Marariel, I love you, I really do.
Anyways, Guess what I found out this week? Affliction Warlocks and Shadow Priests share almost the exact same BiS loot table.
I kid you not, Everything that is a drop (Including Tier tokens, damn you Blizzard) that is BiS for my shadow priest spec, is also BiS for Mara. The only exception here is the weapon. Apparently This Stick is better for a warlock instead of a MH/OH combo. (Granted, my BiS Weapon is a hammer, and my OH probably has spirit on it, neither of which are good for warlocks)
Lucky for us, our guild uses Suicide Kings loot system, which basically means that Mara and I (and the other two priests) will take turns getting the loot we want.. Even though 6 of our pieces come from Majordomo and Rag. /sigh
