The View-model offset sliders in the flight only move down and back. In my opinion, most of the weapons that need to be adjusted need to be moved up and forward instead (like the magnum)
Ideally, they would be adjustable in both directions from default. I could maybe try to edit the config files by adding a negative number, ( Halo MCC weapon view-model adjustment - Album on Imgur ) but the sliders should start in the middle as the default, not at zero. That way view-model can be adjusted in both directions. Not just downwards and backwards.
