I played the game at launch, and have a level 50 Sage. I just came back to the game, and created a new consular but this time I went with shadow. I am more interested in PvE right now, what do each of the specs offer? Is there a preferred spec for DPS? Tank? Any help is greatly appreciated.

What are the priority stats for a Sage? Obviously willpower is #1 but what about after that? Power? Crit?
