Damn! I have to admit, I didn't complete most of the collect-y quests, and I have the bad habit of skipping conversations as soon as I've read what someone would say later on in the game, and I read
fast. With the 3 DLC's, I probably hit 110+, but still, 200 is respectable levels of devotion.
W3 was the last game in a similar genre, and was very well received, so it would make sense people would discuss it. Though there's a W3 thread, missionaries love their preaching. As for a new character - I liked starting anew in each game. I know it can't be Hawke, and the Inquisitor will be busy running the Inquisition (Whether it's a small band or a big, festering organisation, as Trespasser suggested) I can't imagine them NOT being in the next game in any shape or form, frankly, as they'd be risking life or limb (again) to stop/redeem Solas.
Plus, I'd be looking forward to playing a new character. Especially if they do the two VA per person again, I loved playing Dragon Age Samantha Traynor and the American guy, the other two were... meh.
