I don't have time to write up an in-depth article, but, I did an update to destruction warlock stat weights. The default weights did not change, since they are working well already. What I had to do was add an alternate "preset" for the few people who have mostly 372+ item level gear. The preset focuses on getting the 30% haste threshold (7th immolate tick) since that is a substantial DPS boost even at the cost of other stats (hit).
Click on the presets tab to check it out, especially if you want to see BiS sets for the t11 heroic level.
