Ah this is related to my question. Personally I don't like the idea of Chaos Blades much. Mostly because I don't like pushing DPS cooldowns that are 2 min or more. Not that that is a terribly long time or because they are bad, I just don't like feeling like a boss for 12-30 seconds then feeling ineffectual for 1 plus minutes. So I was thinking about taking Demonic with points in Chaos Vision over Chaos blades. My questions was simply is that worth doing on single target fights over Fel Barrage or Chaos Blades. Or more succintly, is Demonic + Chaos Vision a substantial DPS loss on single target fight compared to the other two 110 talents.
