The trailer was fine. It was all very 'pretty mage spells destroying stuff'.
Then we saw someone who looked like Morrigan who sounded not like Morrigan.
If it is Morrigan, I hope it's the same voice actor... I mean, changing the voice actor for Anders was one of the reason his character was a disappointment in DA2 (as well as, personality shift. Understandably he'd be grieving, but it was like the old character was dead. Also his sexuality depending on the gender of Hawke; Bisexual if a male Hawke, heterosexual if a female Hawke - like wtf?)
Does paint a picture of the world.
