AMR is recommending a Legendary ring from previous expansion as the best in slot for a machinelearning setup for my char (klamandar , aggramar ).
and even though i tried manually seting up a haste/mastery /versatility build, it puts me over 32% crit.
We need more information to help you.
We need a link to the gearing strategy that you are using. A link to your character helps too, but we can take a guess from what you gave us - US realm I assume?
