I have to disagree.
I'm in the middle of a Qunari playthrough right now (I actually just made him to get the Trial of the Fool trophy but then... what can I say? He grew on me), and I absolutely love it! I loved talking to Bull and talking about Adaar's parents and how he was raised (and about Qamek and how it actually effects people...), and telling Josephine about the time Adaar blew a bridge (
). I also really looked forward to talking with Dorian since I was sure he'd have unique dialogue, and I wasn't disappointed. Although I have to say a big part of why I like Adaar so much is Jon Curry's absolutely fantastic voice acting.
The only problem I've been having is the camera: there have been way too many instances where I've been staring at Adaar's chest when I should've been the camera is supposed to focus on his face. The character creator is also a challenge (particularly because you have to be really careful with the chin and jaw or otherwise the Qunari end up looking disproportionately small-headed), and it took me some time to get it right, but when I finally succeeded... Hot damn! Worth it!
