I always thought the ending made it pretty clear we'd have to kill him at some point, or at least try. Last time he was left to his own devices a fucking mountain exploded and a hole into another dimension got ripped open.
Edit: Not to make this weird, but if the story is what I think it is, and if "areas" means multiple maps and locals, the survey may have made me diamonds.
Yeah I know, would still be a sad moment. Not expecting a happy ending there, but would be kind of nice given my history with Bio romances, (dumped by Alistair, killed Anders, Thane dead, my protags all get put through the emotional mill!) I'm not sure we'd succeed in killing him, seems like Bio is maybe setting him up to be the next Flemeth sort of character (maybe Kate Mulgrew was getting a bit pricey...). Though, Patrick Weekes does have a history of showing that he cares about player choices and agency (possible to keep Mordin alive in ME3 but only in particular scenarios, possibility of peace between Quarians and Geth but only if certain things were achieved beforehand), so I don't think a happy-
ish ending is entirely out of the question there.
I guess what concerns me more is the phrase 'great evil' - I really hope this doesn't refer to him. Patrick Weekes did a very good job, I think, of making him an ambiguous and even sympathetic character, and definitely not evil. It would be a real shame if he were reduced to moustache-twirling villain.
If there's as much story content in this as there should be given its apparent scope, then it's very good value, along the lines of Citadel even. Qunari invasion and possible wolf hunt are both big ideas, I hope Bioware does them justice. I worry that a ten quid dlc isn't enough for that. Seems like it would take something a fair bit more sizeable.
With a Qunari storyline, I wonder if we'd see Sten from DAO? Also, perhaps some involvement from Isabela, given her connection to the Qunari in DA2, and the fact that Bio has already made her character model.
Edit: also I'm curious, what do you think it is?
