I think part of my perception of Qunari is full-on wishful thinking. Some part of me really, really wants the ultimate message to be something other than "your fear of people who don't look like you or share your religion is 1,000,000% justified. They're perfectly organized, they're hidden among us, they're advancing a secret agenda right under our noses, and their ultimate goal is to convert or kill everyone in their path. Your grandad's incoherent dinner table rant was correct after all!"
I'd love to see more nuance in the Qun, schisms within the philosophy. I mean, looking directly into Koslun's writing, the aggression and war seems tacked on. Koslun was all about mastering
oneself, proselytization, even peaceful proselytization, seems so opposed to that. Not that this has ever stopped religious leaders in real life.

And I would be esctatic if some of their "oops, disavowing time" moments are genuine screwups, rather than their shadowy network of sleepers behaving exactly as planned. I would love if their pushes for invasion are either (1) mostly for show or (2) reflective of some scarcity in Par Vollen, a way of dressing up resource grabs in the Qun to make the aggression look more palatable to their own citizens. I want to see incompetence and corruption, rather than vast, well-planned conspiracy of fanatics.
That's what I'd like to see, and I'll admit that colors my view of their culture. I look for the traits I want to see, and emphasize them.
