I think I am simming something wrong... I've been running DW Frost for the entire expansion. I've been holding out for a decent 2 hander to play around in UH with and compare, or even to compare in 2H frost, but I haven't had much luck. However, I've picked up a few strong DW upgrades over the past few weeks. It had been a while, so I downloaded the latest release version of Simulation Craft and imported my character in. I set it to 10000 iterations and left the rest default...
On a light movement fight, it had Haste at 3.01 vs Mastery at 1.98 on the Scale Factors. When I went Patchwerk, the variable went a bit further... And actually, the "closest" they simmed together was in a Helter Skelter set up where I get Haste at 2.47 and Mastery at 1.89. And even trying to skew it towards Mastery, I did a full sim with 2 targets and achieved Haste at 2.74 and Mastery at 2.30.
Now, I know as more targets are available Mastery continues to get better... But these numbers suggest gemming/reforging haste. I'm just trying to figure out if I'm doing anything incredibly wrong with it, or if Haste would be stronger right now (and then prioritize Haste -> Mastery -> Crit).
Here is a link to my armory, just wanted to get some thoughts before going off and testing it in LFR this weekend =/
