Feel like I'm missing something because everything I've seen and read thus far (including the recent Blog update about her character) doesn't have me even remotely interested in her. She feels...fake. Her beauty is artificial and her personality sounds irritating.
Her accent wasn't all that great in DA2, true. Little nasally. Maybe that's why it's a different voice actress for Inquisition. You can actually hear her new voice in the extended Demo they did for PAX, EXPO, etc. It's a little more lilting and the french inflection isn't as front and center. I'd say it's closer to a French Canadian/British mix then a pure French; maybe to highlight her Navaran roots better. Also, I love French accents on women, unless it's particularly screechy which even Cassandra's from DA2 wasn't. I mean, she wasn't Isolde for Pete's sake. "Teeeegaaaan!" Anyway, link to the full demo below where her voice is audible from the beginning.
