Intended at launch as a feature. It's being worked on, actually.
Are you sure?
Please don't misunderstand me, I really want the feature to determine the starting class of the NPC companion origins as e.g. I don't want my Red Prince companion set to warrior and feel I have wasted attribute and talent points if I decide to teach him rogue skills. I just don't want to get my hopes up for what to me is a very important feature

Love the origin stories so far, but dislike the class system forced on the companions.
