It wasn't always a 30fps game. Once upon a time there was a 60fps trailer and a 60fps target. Yes some are still butthurt about it. Hell even the 2014 trailer looked better: less details, less effects (maybe because of the 60fps target?)...but more clarity in motion. More is not always better.
We are in 2016 now, flawless still screenshots don't work anymore, at least not on me. There is such a thing called temporal resolution / clarity in motion -> it's the main reason why PC master race is a thing. And now at 1080p more than at 720p, I believe 30fps with heavy filmic blur (and high input lag, don't we forget that) in 2016 is not tolerable anymore.
Also as you said it's a 30fps game so at least they could give us a better quality motion blur (and less heavy for god sake, it's very noticeable for some!).It's like they don't care about the image quality in motion. Some 60fps games use better quality motion blur nowadays.
Finally it's possible to do a 30fps motion blurred game having decent clarity in motion, but only if you use a light and high quality motion blur which is clearly not the case here.
