As no one actually answered the original question from the OP I will.
In terms of 2h priorities nothing much has changed for us in MoP. But you will want to prioritize procs on Oblit so much more than what was previously required.
For example wasting a good few procs wasn't that bad prior to MoP but considering the disparity in damage that both FS and Oblit have between each other you can't go throwing procs away to do competitive damage.
As a couple have mentioned Sims on patchwerk conditions do not favour us greatly this tier, mainly down to no down right abuse-able trinkets like 100% crit for casters or RoO for agi's. Though under real world conditions DKs are still favourable you just need to really push the boat out to be able to match say a mage or lock in a fair scenario.
