So I'm bored, waiting for swtor just like everyone else, and I've been messing around with the skills available for the sith sorcerer (which I'm gonna play), which spec you would guys use for PvE? Personally I'm gonna try using Madness & Lightning.
Madness + Lightning [heavy reliance on dot spells, similar to warlocks]: http://www.torhead.com/skill-calc#201Zfzr0dZfrbRsokrc.1
Lightning [Significantly less reliance on dot spells, similar to mages]: http://www.torhead.com/skill-calc#20...odoMutzZcM0M.1
Corruption [Healing]: http://www.torhead.com/skill-calc#20...0dGzZf00MZoM.1
Note: These are probably far away from being optimal, I'm basing these on previous builds I've seen done by others.
