Fine as long as it's not shirtless teenage werewolves.
Meh, Michael J Fox was doing that long before it was cool.
By "cool", I mean almost as nauseating as day-glow vampires.
I would also be very interested in seeing this, however how would they do it without you getting a major advantage. They would have to have like an elven option for people who didn't allow the werewolves to nom on the dalish during the first game. I'm quite pro anti-dalish so I am fine to let them feed on some more in the third game if they allow us too. :/
Personally, I don't think they should.
Like with Maelon's horrific work on curing the genophage during ME2. If you destroyed the research, Eve died.
Speaking as someone who never sided with the werewolves per se, I didn't side with the Dalish in that issue either. That wouldn't end the curse, and those Dalish of his own clan would still be victims of what was born of Zathrian's rage.
If it's something that's only available if you sided with Zathrian, then by all means let that clan of Dalish be available as a potential asset for the Inquisition.
If you lifted the curse, then I think it would be fitting if neither were available for whatever reasons.
