So, I was under the impression the Duergar subrace was ECL+1, but here on PotM it seems to be +2. Is there any particular reason for that? Compared to an Aasimar or Tiefling, who are also +2, it doesn't seem an equal balance. If the argument for ECL+2 on Aasimar is that they get the human bonuses in addition to the other stats, then I really can't see why Duergar is +2. If it's the Light Sensitivity, I don't think -1 AB really accounts for a whole level.
