I just created a dark hunter and the idea of trap disarming is pretty neat for a ranger. Kind of an urban hunter instead of a traditional ranger, very cool. The restriction to favored enemies is thematically perfect for this idea.

I do have one thing to note, when I went to train to level 2 I noticed the four points I put into Disable Device and Open Locks had been reduced to 2, like it was considered a cross class skill still?
