I have to say that I don't like playing humans. I'm a human every day of my life, so why would I want that in a fantasy game? So if tehre is anotehr option, I will mostly take that - but I did all Origins to get an insight (and I have an active fCousland at the moment, whom I actually like, so maybe she will see the end of the game...)
I like Dalish Elf the most. I just love the concept of elves in DA and I do like the Origin story. I'm still sad, Tamlen died
Dwarf castless is great too. It's much more fun than the dwarf noble. I like that 'in your face' attitude of my castless girl.
Female city elf is nearly as great as the dwarf commoner, despite being a bit unrealistic, like someone mentioned before. On the other hand, if I remember correctly, that serial killer in Kirkwall, who was son of a high ranking politian, could go on killing elven children for years, despite the fact, that his crimes were known. But he could go on, because he was a lords son and his victims were 'only' elfs. I guess it's not that different in the ce origin. Maybe that Arls son (I forgot his name, I never listen to him and kill him as soon as possible) took the opportunity, that the king and many guards were away. It did not feel, like that sort of incidents were common.
I don't like the human noble origin that much, it's kind of boring and the family is a bit too perfect. It's nice, that some character has a functional family, but they went a bit over the top with that (maybe to make up for the lack of family in some of the other origins - the Dalish is an orphan, the dwarf commoners mother is an alcoholic, the dwarf nobles family is a bad joke, the mage has no famliy, the city elf only a father left). I always wanted to finish at least one playthrough with a hn though, to get some of the specific content, you only get with that origin, apart from the marrying Alistair and become queen option, that's a nogo. I deeply suspect, my rogue Cousland will end up with one of the rogue companions, most likely Zevran.
Mage and dwarf noble are both ok, not that great, but ok. In the mage origin they didn't do a great job in establishing Jowan as your best mate. You did get that best mate feeling with Tamlen in the Dalish origin or with Joris in the city elf origin or even with that red headed knight everyone seems so fond of in the human noble origin (the one, who should become GW , forgot his name, but he seems to be a fan favorite). WIth Jowan, I never had that feeling and I guess, that's the reason, he is not working well in the mage origin. I tried to be his friend, but nowadays I normally go behind his back to Irving and I really don't feel bad about it.
And in the dwarf noble origin, the family is a bit too unlikeable for my taste. I get it, that your character and Bhelen are supposed to get along well before he starts killing off his family, but to me it feels like Jowan in the mage origin. I always thought, it should be a big shock, when you find out, what Bhelen did, but somehow, it did not work for me. At the end, most of your family is dead or dying, but I feel nothing (well, a bit of anger about that stupid noble caste, but that's it)
