Warrior of Darkness: alter ego or something completely different?

[Iris_BP]

SInce the introduction of WoD at the end of HW main story quest I always thought that it's WoL alter ego. Which made sense for me, because it would've deepened the character portrait. During the MSQ you're so absolutely lawful good, never do anything wrong (even if you'd like to), aureole of saint shines above your head all the time so I thought it would be only natural to show the other side, that you have some darkness in you too. Alas I was wrong and we see a midlander warrior and his "CGI team" in the preview painted in black. This made me a little bit sad, because honestly the personality of WoL is still shallow. Granted, they made you less of an errand girl/boy for scions in HW, but that's not enough! I guess it's just my wishful thinking, but the introduction of WoD and Bishop's words "What are you?" made me think that we're not so onesided of a hero and now my hopes are definitely fractured if not shattered to pieces.
On a side note I'm interested how will they deliver the "CGI team" as servants of the dark side? It seemed like they were always the incarnation of WoL team (hence my thoughts about alter ego). We don't have much time to speculate since it's only two weeks before release of 3.1 but I'm still interested in peoples opinions.
