Hai there.
I've been Affliction from MoP launch to 5.2 release, when I decided to go Destro due to the better damage.
However, I got the Thunderforged version of Unerring Vision of Lei-Shen yesterday, and decided to go Affliction again. I figured that as Demo, you could get a 100% critting Doom on your target if you're Demo, which could increase my DPS a lot. However, I'm not sure what would rank best with this trinket, Affli, Destro or Demo?
