Yeah, I found the same thing. I was pretty excited when I heard there was a FPV option since that's how I prefer to play, but it definitely feels awkward. I'd personally like to see the arms/hands of my character like FPV normally has in other games. Running and walking is also looks super smooth (no camera bobbing all over the place) which feels very unnatural. I'd love to see any/all of the improvements you mentioned.

That being said, I'm glad they even included a FPV, since I know that's not how a lot of people choose to play. I probably wouldn't put improvements to the FPV very high on my wish-list either, since I have only really use it when I'm running around the world or taking screenshots. I doubt that the amount of effort needed to creat a 'proper' FPV would really pay off in terms of player satisfaction though...

(We can hope though!)
