People like different groups; you'll find fans of the templars, the Chantry, mages among the fans of Dragon Age.
If you think any fan of the elves thought they were perfect, you clearly know nothing about the fans of the elves.
No one thinks they are perfect. No one ever thought they were perfect. It's hard to take you seriously when you make these kind of accusations.
Some people, like myself, don't think that the narrative has been balanced. I think it's shown favoritism towards the Chantry of Andrastian and Andrastian humans.
When I say perfect I mean that there is a kind of meta expectation that everyone will want to root for the elves and they are the classic oppressed group. I think many gamers playing this game in Origins and DA2 were more or less sympathizing with the elves, and the reason they are oppressed is nothing other than classic racism and ignorance on the part of the humans. The elves did nothing to deserve their plight except exist. They were free of guilt for their larger diaspora. Anecdotally, individual elves, obviously, aren't perfect, but by and large, they are victims, 100%. Inquisition is the first game in which we are introduced to a possible complication of the origin of their circumstances.
So, no, I don't think there was favoritism toward the humans or the Chantry. There are indeed fans of the chantry and fans who lean toward Fenris' views, but from a basic reading of any Dragon Age forum or fandom in general, the mages and apostates always seem to be the most popular faction, if only because Morrigan, Anders, Merrill and Solas are so overwhelmingly popular with everyone. Even Alistair, a former templar, has moderate views compared to his templar peers, he even agrees to a dark ritual for crying out loud, and he mentions in Inquisition that he wanted to help the mages initially. Even Leliana, a popular character, advocates for greater acceptance of mages, to the chagrin of Vivienne, and Cassandra explains she is also moderate and wants to confer greater respect to mages under the Chantry.
When Morrigan appears in the Kocari Wilds for the first time, Daveth and Jory spout the typical "oh no, it's a witch, she'll turn us into toads" spiel, to establish the lore which says that Thedas is a world where non-mages fear mages, and in line with the trope of ignorant peasants fearing outcasts; but all this meaning in this situation, relies on the assumption we are informed of this trope. That trope includes a modern recognition that peasants feared 'witches' because they dared to dabble in science - that trope includes a modern recognition that fear is based on lack of knowledge. All of this positions us to sympathize with mages and to assess the Chantry as an outdated institution.
