I'm pretty comfortable with Shadedancer but just in the process of learning Assborn. It seems like in a raid setting shadedancer is 2-3k higher than assborn, while assborn has the benefit of being a poison spec. But I'm not that comfortable with Assborn so the results may not be accurate. For those rogues who are very good with both specs, what are your differences in dps between the two specs?
