Yeah, they could easily fix that by adding different types of brows, eyes, noses and mouths. I mean, they could do that in the trilogy, why not here? We're basically stuck with the types that comes with each presets.
because the game is rushed, as also evident by the fact that we'll get more character customization options a bit later on in a patch (meaning Bioware Montreal somehow didn't have the time to make a up-to-standard character creator in time for release)
