I don't actually mind being human, given the nature of the story it does make sense to be human, seeing as the factions are between human only, and mostly human.
David Gaider I have mixed feelings about. He has the ability I think, but I dislike his arrogance. Although I imagine a lot of it is probably lack of patience with some of the more crazier fans constant demands.
My largest concerns at the moment are that it will be as railroaded as DA2 and ME3, where we do not feel like we have any say in what actually happens. Granted a lot of the older games are not as free as they seem, but the designs allowed us to feel like the game was a lot more unique. Especially the different origin stories and the perspectives they gave.
My other major issue is that the game will probably feature poor paraphrasing and auto-dialogue. They knew fans wanted choices and better options but still did both of these poorly in DA2 and ME3. In DA2 the options made practically no difference to the outcome of the conversation, they simply changed the tone. Whereas in ME3 Shepard apparently grew a mind of their own, and decided they had all sorts of opinions that completely clashed with how I imagined my character to be.
My last major concern is that things will be inconsequential like in DA2. The main story is about Templars and mages, especially the way mages are all kept on a tight leash and always under suspicion. Yet playing as a mage makes absolutely no difference for the most part beyond a few lines of dialogue that do not impact the story. Considering the nature of the story, it actually breaks it quite badly.
I would say that I am cautiously optimistic, but am more than prepared for disappointment. Or in other words, I really want it to be fantastic, because I love the series and the world they have created, but will not be surprised if it isn't.
I am currently replaying the games actually. I'd say my largest dislikes between the two are that Origins can drag on too much in certain areas, whereas DA2 feels too constricted, and forced. Varric is easily the best thing from DA2, hell, I think he may be my favourite computer game character ever.
