Hey there. I have spent probably 10k upwards going from;
askmrrobots - Default PvE Spec/Hit Cap spec
Simcraft stat weights plugged directly into AskMrRobot.
However, I have found no matter how I simcraft, I seem to always get different results. Some favouring Haste and some favouring Hit, and even some increasing the weight of Crit.
I have given up slightly and gone for the hit cap weights on AskMrRobot. But I've come to you guys for some help, as I'm sure I am doing something wrong to be getting these varied results which cost a fortune to switch from and into. I have read the guides for simming, but by those standards I should be getting one set of weights and not a completely different set when re-simming.
Please tell me if I am wrong. And feel free to ridicule my armory;
SimulationCraft ( not simcraft ) stat weights will always differ, but will stay within the given error boundaries 95% of the time.
So without giving actual numbers, including the error reported, such a claim is pretty meaningless.
Oh and if you compare scale factors for two different gear sets ( eg. one with hit cap, and one with full haste ), you will get different scale factors. That has nothing to do with SimC, that's just how linear approximation works.
