That could be it...though I'm somewhat inclined to think they wanted to try expanding in a direction that seemed like it had a lot of praise when done by other developers (thinking of Skyrim and Bethesda here).
Given how different it is from the first two DA games, I'm hoping this game had elements of experiment to it, and having seen the differing reactions to the open world set up, Bioware will now have a better idea of where to draw the line between linear maps and open world maps (like...desolate places like the Hissing Wastes make sense to have an open world set up, but the Emprise du Lion maybe didn't need it quite as much, or at least to the degree it was decided).
I do think given the massive amount of information that gets tossed around on the forums, it's probably not easy to hunt it all down and figure out what's most relevant. I wouldn't want that job.
The attractiveness of characters is subjective. I personally found the Origins males more attractive, though I like the Inquisition one's just fine (those voice actors....I like), so I don't think that's a matter of feedback not being understood/correctly stated, but more just "Am I going to get lucky this game with the appearances of my LI?".
Sure let's see some busts. But no bust enhancing chantry robes please. That was just weird XD
I'd love to see the return of desire demons (and some male ones too, because why not?)
I've seen a lot of people who feel that the Qunari as a whole were seriously retconned, but I don't know. I never got the impression that Sten was meant to be the final form the devs had envisioned, nor a holistic representation of Qunari society (merely one facet of it). I think it would be really cool to see multiple Qunari actually interacting with each other, rather than just one Qunari deigning to talk to our PCs, who aren't really all that knowledgeable about different cultures anyway (or even their own....Lavellan Inquisitor: "So this 'Mythal'"....whose tattoos I have on my face but why would I know about that person. Eck). So I guess I think there's a lot of potential to make the society even more interesting, but we haven't been given the opportunity to actually see it in action yet.
Losing the Origin was a bad idea, but I think it was one that came more from having to shift plans. I can't say for sure, but I get an impression that they meant to have just one main PC, the way they had Hawke, and switched gears after the demands for multiple races. Perhaps the complaints should have been more specific and stated "Origin stories please", but I would have honestly thought that would've been implied.
Blooooooood magic. I need it back. I hope we get to actually use it as a story tool in future titles, instead of my Hawke going "Oh yeah blood magic's sooooo bad...I'd never use it" (used it literally one minute before)
If TL;DR, I think it would be a good idea to praise specifically what's done well, in order to see it return, and specifically critique the issues in the game and explain where we're coming from, so that's it's very clear why they need improvement.
