Jahan and Madora, at their starting level of 3 (which I wish was lower - see the rest of this thread) have the attributes of a level 3 character, the abilities of a level 1 character (in Jahan's case he doesn't even have that), and lack the talents of even a level 1 character.
Unlike the real characters they don't pick up any traits while adventuring (although were advertised as having traits), which already puts them at a disadvantage.
I think there's some questions here that only the developers can answer. Such as, are the followers (which are rarer than henchmen) supposed to be as powerful as the characters they accompany? Someone pointed out that the main characters should be better because they are "Source Hunters", but (again) Madora is a Source Hunter as well, and yet much weaker in comparison. Jahan is not a Source Hunter, but he is clearly something else.. something special. Not less, just different.
