Shadowcraft (4.2 Experimental) is currently telling me that optimal gemming means 4 Delicate Chimera's Eye. It also seems to think that Cogwheels in an Engineering helm should be in a specific order :P
Regemming Agile Bio-Optic Killshades socket 2 from Quick Cogwheel to Fractured Cogwheel
Regemming Agile Bio-Optic Killshades socket 3 from Fractured Cogwheel to Quick Cogwheel
Regemming Flamebinding Girdle socket 1 from Delicate Inferno Ruby to Delicate Chimera's Eye
As you can guess I've got optimal gems otherwise, with the "fourth" Chimera Eye substituted with a Delicate Inferno Ruby. This issue wasn't happening before tonight.
It's also recommending me be at 1321 hit rating, 11 below the cap. Is this expected?
