What good is duplicity for a tank? I mean, how often do you maul to make it worth the points?
For 23/1/17, its worth the one point in there, especially after the changes. Before, it would only seem to proc from using Saber Strike or Discharge, now it has a chance to proc on almost any attack: Thrash, Shock, Force Lightning. Keep in mind, this is from a purely PVP standpoint. In PVE, if you're the tank, the mob ALWAYS faces you unless its stunned, so you don't ever really have a chance to use Maul.
