Using the 2H-ICC pre made I get 15.891 DPS and if I replace Boots, bracers and the hand enchant: 15.999 DPS. I don't know why our results have some difference except if you forgot to change the hand enchant.
Anyway, the long awaited new version of the sim is ready for release:
1.2.1.7 Release notes
* UA GCD fix
* Rune Strike is back on frost presence.
* New: Ruby Sanctum gear.
* New: Scenario editor. This is the place where you set up fight lenght, some events like adds that pop, boss unreachable.

I have updated the Item Database because it was lacking of the socket bonus on the Penumbra Pendant. You may want to re-download the package and just overwrite the file ./gearselector/itemDB.xml.
