One thing I would like to see BioWare steer clear of in ME:A that DA:I had in spades was the complete 'humanification' of the setting. What I mean is how DA:I practically drained the 'other' element out of Thedas in favor of focusing on the 'feelz' and human issues; and by human issues I am including the Dwarves, Elves and Qunari as well.
Compare DA:O/DA:A to DA:I, in the first game and its expansion we got to see and interact with Sylvan, Werewolves, Golems, Awakened, and various demons and spirits. Even the animals of the first game had a unique spin on them; Mabari possessed near human level intellect, and dragons were incredibly cunning, being capable of even using cultists to protect their nests.
Flash forward to DA:I and all of those elements are missing, Sylvans get a crappy Plants vs. Zombies themed mention in a random letter. Werewolves and Golems are nowhere to be seen. Awakened aren't even mentioned at all, despite the possibilities that they could provide the narrative, and the Spirits/Demons of the game are all (save for two very, very human characters) are just mindless monsters that want to kill everything on sight, like simple Rage Demons. The game doesn't even bring up the fact that Pride demons are on the same levels of humans in terms of their intelligence and scheming; nope just mindless "Rhaw! Smash!" monsters. The animals don't fair much better either; Mabari are reduced to stupid packs of wild dogs that attack anything on sight, and Dragons, the namesake of the series, are transformed from cunning creatures with an alien intellect into a bear with wings and a breath weapon.
I would like to see ME:A stay as far away from this 'humanification' as possible; especially since it is a science fiction setting and has even less excuse for everything being human centric than a medieval fantasy does.
I agree with a lot of what you say, though I think that ME1 had a good balance of aspects that were wondrous and alien (like the Thorian or Rachni) and elements that were clever representations of real-world political issues (such as secularism and the hangar preaches, genetic modification, corporate intrigue etc.) - the latter is 'humanification' done right as opposed to done poorly.
A good example of it being done poorly is with the geth in ME3. ME1 and ME2 did a good job of representing the geth as an alien intelligence, an alternative form of being but also simultaneously hinted that they had evolved several more 'human-like' elements (such as Legion's seemingly illogical reverence of Shepard and the heretics learning to deceive). ME3 threw a lot of this out and had Legion and the other geth aspiring to be identical to organics. This was a shame as not only did it unravel their mystique, originality and alienness, but it also suggested that groups with very different ideas and ways of seeing the world have no way of coexisting until one side adopts those of the other. This ran completely contrary to what the geth had been struggling for as mentioned in ME2: to retain their unique and different way of being but to nevertheless make peace with the other races.
