And yet annihilation has most of our dot talents. Sorc dps trees overall aren't done well. The wonderful Affliction talent in Lightning made this obvious. Bioware does not like the Sorc advanced class, its as simple as that. Operative at least has burst to make a dent in people within a short duration. (Op being another class that can heal and dps, supposedly.)
Bioware needs to add a support role, because, lets face it, we exist to play music on a lute and look pretty.
