The combat's not that spectacular, I'll agree with that. I play it on easy for a reason. I mainly play Origins for the lore, the choices throughout the story, the sheer amount of choice when it comes to developing your character, the amazing companions, the romance system, etc.
I'm not entirely sure what woman from a portal you're talking about. I can't really think of any "lore dump" characters because a lot of the lore can be found through scrounging for books and whatnot. The in-game codex has over 200 entries in it, as an example. There isn't really a need for a lore dump character due to this. Sure some characters will talk about lore, but that's usually because it's something they know a lot about. Most of the companions you find come from specific backgrounds and really only talk a great deal about said backgrounds. Like Wynne is from the Mage's Circle, so most of her lore dialogue revolves around the Mage's Circle. That sort of thing.
I also appreciate the fact that in Origins you can indeed be pure evil, and even though in the end you're forced to fulfill destiny there's multiple ways to tackle it and you don't have to be the one to do it, unlike, say, Skyrim for example where you are absolutely the chosen one and are forced to be the one to kill Alduin.
