The issue i had with the default view was that it was too narrow. I know it's easily fixable by zooming out, but still, it's better to have it right at the "correct" Field of View by default. I edited the Views.lua and tested and found that for me to look at the horizon on the HUD i had to watch slightly upward (which that is not comfortable), so i edited the file again to have my line of sight right on the horizon. I find it much more comfortable now. More natural. I've never been in Mirage though. :)
But as you said, we can tweak the view to our liking. :)
