Stam sorcs are good now, mine kicks ass ! But i see people saying stam DKs have higher damage. How is that ? They have 2 stam friendly ultimates and 2 poison DoTs. Stam sorc has no ults but has 1 DoT (Hurricane) and a real good sustain skill (Dark Deal). Stam sorcs are way more mobile than any other class with Streak and Expedition stacking (Hurricane + Bow Passive), the only thing really lacking is not a spammable, because otherwise no one would use the weapon skill lines. I would see a couple of utility abilities and debuffs to through onto the target. Otherwise stam sorcs are very viable.

Pets and toggles are the worst possible things about a sorc though IMO. Take those out, swap them for REAL abilities and you have yourself a useful and decent class in group play.
