As far as I can tell my negative percentage doesn’t seem to match up with the other posts that I could find (corruption cap, order of specs). Is there any other reason that it could be suggesting a DPS decrease? I tend to find that AMR really likes the pocket sized computation device for both my warrior and my restoration druid. Is there perhaps a bias towards it, or do other sites maybe undervalue it?
I tried the reset suggested by yellowfive, and it now seems to correctly recognize the item level of my Heart of Azeroth. And it seems to be making more reasonable suggestions (it still likes the computation device but the active can be crazy strong as well).
