Every single thing the Venatori did throughout the game. From making people slaves, to turning people into monstrosities via Red Lyrium, to murdering hundreds if not thousands of innocent people, to helping Corypheus try to destroy/conquer the world.
I'm not arguing that the Venatori took slaves, just that it confuses me because it's inconsistent with Calpernia's personality. She's an ascended slave, and it's been a while since I've done a playthrough with her, but I seem to remember her buying slaves to free them (at least more or less), and disintegrating someone who harmed them. She also didn't want a former slave to do a menial task for her; she'd do it herself. Did I miss something, or is this just inconsistent?
I think DA4 could just focus on the inquisitor again, seeing how this game ends. Making possible for him to drink from the well would be quite useless, if they change character again.
I really hope so. They could still have a new location and new companions if they wish. I don't feel like the Inquisitor's or the Inquisition's story is over, especially given the fact that the Inquisition cannot be disbanded and the Inquisitor is not given the option to retire. I'd be quite annoyed if both are pushed to the sidelines in the next game considering the lack of choice we had at the end in that regard.
To me, it seems like taking away options that really should be up to the player should only lead to more content, meaning: If we can't disband the Inquisition/retire as our characters would, they better have another game with the Inquisition. I also want this because I'm getting annoyed at our protagonists "mysteriously disappearing", and I would be vexed if that happened to the Inquisition, which is now almost a nation unto itself.
Lastly, and foremost, I am sick of character-whiplash (having to meet new people again just after becoming previous companions' friends/having to build a new character right after finally getting some character development). Even though the Inquisitor is my least favourite protagonist of the 3, I'd much rather continue her story, with her friends, and develop her and their characters than have to start yet again.
