You know, I was all set to play a Dalish Mage for my first Inquisitor... but after seeing this footage I'm starting to waver. 
Stealth, thrown daggers, backstab, chain jump, evasion... it's gonna be tough.
I really, really want to see a Knight Enchanter and Assassin gameplay.
HOLY CRAP! I think you're right, there did seem to be a dagger throw at one point. If they finally let us throw daggers in gameplay, finally, then I think this is going to be awesome.
I loved rogues in DAO and definitely liked them less in DA2. But DAI's version looks to be far surpassing both so far.
