Could you include hardmode Muradin in this list? Gunship is basically the heroic loot pinata, and when I ran SimCraft for my lock, DFO+Heroic Muradin's was better than DFO+NMIC by 167 DPS. (1000 iterations, 100s fight, Patchwerk style, all raid buffs on)
I also wanted to note that SimCraft doesn't seem to import Muradin's correctly. The line is:
Which doesn't include the static +152 crit. So I did change that line to be:
Without the code change, using Heroic Muradin's is a 4 DPS decrease. So considering the requirements of getting the most of NMIC, I would still advocate using Heroic Muradin's.
