Assassination or Combat for PvE
Getting mixed debates on my server for which is best. could any of you guys shed some light on it for me please.
By and large Assassination, with a slight leg up for combat at high gear levels and on specific fights or strategies involving AOE burst (e.g. quilen on Iron Qon heroic).
Spec assassination and be happy to play it 98% of the time.
Herald of the Titans
Combat and assassination at current are discussed in more depth HERE. Beyond that, as Lachtobi points out, you've got the same tools as anyone else to analyze the class's specs.
Closing this because we don't need multiple threads on the same topic.
