Well i suspect the alien males were more interesting to write for, design and animate. In all fairness to Bioware this is a primarily male orientated career and human male characters were hard to find all that interesting. Both Kadian and Jacob have coped critisism for being boring but it may be Bioware people were simply not all that interested in developing them when they have an alien to have fun with.

In all fairness they probably felt getting more into Kadian would make him seem whiny, so they pulled it back and made him quite professtional and someone who keeps all lot of feelings inside and has trouble expressing it.
