God, this thread updates fast. Seems like some days, I can barely catch up...
I loved In Hushed Whispers. It was one of my favourite parts in the game. It made me suffer watching what they had done to Leliana, it made me thrill when ugly Leli sacrificed to save the world, it made my Warden's proud of normal DAI Leliana in the aftermath when she said it was a good bargain sacrifice one's life to save the world. I like AUs and time travel plots, but those are things that must be done with extreme care, more so in a fantasy setting. We don't have a Tardis, or a DeLorean and even magic needs some kind of internal coherence to be well written.
Yeah, both Hushed Whispers and Champions of the Just are probably the best quests of the game. That being said, I'm just hoping they don't over-do the time travel stuff too.
I believe the "Shrieks attack the camp" encounter occurs after you've recruited four out of five of the main story quests. That's when the Archdemon realizes you might actually be a threat and sends a hit squad after you.
Precisely. It doesn't really matter what order you do them in.
I love how the Mahariel origin has an impact on all the heavily story-driven DLCs in Origins, as well as Dragon Age 2.
It may not have been involved in the main story as much as let's say, the Cousland and Tabris origins, but I'm glad the devs found some way to make up for the lack of content. 
That's a really good point, actually. never thought of it like that before. If nothing else, it meant we got Merrill in DA2, so that's a story decision that turned out for the better.
I don't recognize the existence of DAO's Merrill. That's some imposter claiming to be Merrill.
It's all about the accent. That sexy Welsh accent...
