I read somewhere (I think here...can't go to the Steam forums anymore..../shudder) that in the EA you could respec the origin characters or was it henchmen? I can't recall. Has there been any word if that will be the same at release? I'd prefer to run my own stat created classes (I fully understand we can't change the characters looks, race).
You will be able to respec any character in the game, including playable Origins characters at launch. To do that, you'll have to meet a specific NPC early in the game. It'll likely have a cost (gold, etc?)
