And yes the nightmare and hard mode versions have the same HP. So I think its unintentional on Bioware's part but it is the same. Thereby making it a bug. Well on second thought maybe its not a bug b/c the nightmare mode achievement is non-existent. Either way its the same and maybe later they'll upgrade nightmare to nightmare difficulty.
