so i have been looking at my character at wow heroes couse i find it to be a cool that you can see thinghs with your char as dps ranks etc. my question though. it shows what stat prio i got is that taken from what gear i have and have gemed for. or does it actualy do a simcraft on my char and look it up?
It likely uses just a predefined stat priority. It doesn't have the stat weights so its likely not simmed.
It doesn't appear to show the stat priority that one has on their gear but I could be wrong. One way to tell would be to change specs, logout, and recheck.
