I'll disagree with you that the drama is equally distributed between guys and girls. If we forget ME series then there is still all the different outcomes with Alistair romance such as he dumbs you if he becomes a king. Well there are options that you can become his queen if you are human noble or his mistress but then you will have to have high persuading score. He also leaves you if you choose to recruit Loghain and then there is the DR. There hasn't been any occasion in DA series that female LIs would have to do something similar like DR. Anyway I think it's a good thing that there are different outcomes with the romance but if you add something like DR to that I would say that there is quite a lot drama there.
There is also the decision in Adamant where you have to decided who will stay behind and my choices were Alistair who was with my warden and Hawke who was with Fenris. So one of the romances will end there. Of course there is a small change that there will be a DLC where it's possible to save the one who was left behind but I wouldn't count on it and there isn't anything equivalent if you romance a girl in DAO.
I have no problem with the drama if there are options. Alistair romance without DR would have been ok and saying without DR I mean that you don't have to do it for you both surviving the last battle. Alistair with DR is acceptable. Thane dying no matter what was ok because I expected it to happen. But I don't want anything similar in near future because my tolerance towards those kind of romances is quite low. Jacob cheating you was awful. Solas dumbing you and coming back would be lovely, but if he comes back and says that you can't be together would be frustrating.
I'm not going to go back into my thoughts on the Alistair romance in Origins. However, I do want to comment on the things people keep bringing up about Adamant.
For one, I'm sure the devs did not make Alistair a Warden option, or develop the choice made in the Fade, with the idea in mind that it just makes another tragic romance for women. They built a story involving the Wardens and Hawke. It makes perfect sense for Alistair to be your Warden contact given the fact that he's a very high ranking member of the organization and that he would totally oppose what the Wardens are doing. If they had defaulted to Stroud for every game, I guarantee people would have been up in arms asking why Alistair (or Loghain) was nowhere to be found. And in the long run, Alistair being in that role makes the most sense. He's high ranking, famous, and charismatic, just the kind of guy you DON'T want talking your troops out of following your crazy plan to end the Blight.
While I disagree about the Dark Ritual thing and the mistress thing, I can get behind why a lot of folks feel those are bad endings. But I'm not sure I can get behind Adamant being put in the same context. Being a Warden is dangerous. I think it's unrealistic to feel death in the line of duty ten years after Origins means that the whole Alistair romance is a bust. Death is a constant risk for a Warden, and for any soldier.
Of course, I killed Hawke in the game where Alistair was my Warden.
I have a pile of Hawkes, but there's only one Alistair.
