I downloaded the latest version of Sim Craft and ran a T15 Heroic BiS sim for Assassination Rogues, and it was giving me an 88-89% uptime on Juju.
Anyone have any idea if it's me, or did Simcraft get a bad update in regards to Juju? If the mistake is on my end, I'm not sure what I did. I just ran the pre-set BiS list. I was expecting to see it in the ~25% range like everyone else, and bout spit my coke when I saw 88%.
