Hello,
I want to sim my DK with the Runeforge + Sharpening Stones but when i select sharpening stones, the runeforge disappear.
(In game we can have twice)
Did you have any solution ?
Thanks in advance 
In the simulator, you can click to the right of the runeforge to pick a temporary enchant and simulate it, as in this screenshot:
If you are talking about the optimizer… I don’t think that I completely finished the feature for optimizing temporary enchants now that I look at it. They turned out to be so inconsequential that it fell to the bottom of the list. The difference between shadowcore oil and a sharpening stone is extremely minor.
Hey there !
Thanks for your tips with the simulator 
It’s ok for me
