It is the Inquisitor's time to shine, but I think it would be cool if we had a small segment where we got to play as Hawke and the Warden, before they joined the Inquisitor for a short thing and all the dialogue we get out of them that we don't control is the dialogue shouted in battle as was done in Origins and DA2.
No real conversations, except for Hawke who could respond only in the dominant personality that carried over from DA2, or from playing as Hawke for a very brief segment.
I think it's a great idea if we got the three heroes of the Dragon Age to work together to fight the big bad, and only for fighting the big bad, but I also think it'll be very hard to pull off.
I do know that no matter how it's done, it's going to ****** someone off simply because there are so many fans.
