And yet that is not always possible. Gameplay cannot always account for everything that can occur in a story, and vice-versa. The concept of gameplay/story separation is an essential ones for video games in general, simply to make them work.
A pity, I think, but as I said earlier, I think we all knew that would be the case, because the lack of that in DA2 is most likely due to it having been rushed out the door in barely over a year, not due to Bioware actually changing their MO.
Actual answer: as mentioned above, most likely because the game was rushed, and that was one victim of that. Ironic that this should be a plus for me, I suppose.
My personal answer: don't. Simple as that.
That's the way it's intended, of course. For me though, it just comes across as a character that isn't really a character, yet is put into an important position in the story anyway. I want the game to tell a good story centered around interesting and/or enjoyable characters, not pretend that I'm in control of the story when it's impossible by the very nature of the medium for that to be the case. I see attempting to emulate tabletop RPGs in video game ones in that manner as a waste of time which merely holds the stories back.
