I understand why the mooks are blurred out, I just disagree that they're unimportant. If they're important enough that the MC needs to interact with them, they're important enough to be rendered. I'm not keen on it when other games use mannequins, but at least they only use them for literal background characters. Leaving NPCs we're talking to as blobs (while calling attention to their supposed uniforms no less) is, IMHO, an extremely lazy solution.
But it goes beyond that because, again, the game keeps playing up the idea that we're choosing to follow Enna to preserve our (un)life. Well, what kind of life is it when the vast majority of people with whom we could interact will be nothing more than faceless blobs? How is death not preferable at that point?
