A SWTOR port of this: http://simulationcraft.org/ . Original development discussion was hosted primarily at MMO Mechanics (now defunct), later moved to https://code.google.com/p/simulationcraft-swtor/ (now abandoned), moved to a Google Groups mailing list at https://groups.google.com/forum/#!forum/simulationcraft-swtor (now inactive), and had it's final death throes at https://github.com/simulationcraft-swtor . It never got to the point of fully simulating all classes or specs, but Deception was one of the ones fully simulated from the start.
