I'm a bit concerned as well, as far as the latest flight for me zooming was broken and inconsistent, switching to secondary weapons was inconsistent, I couldn't pickup any weapons on map.
Check out the Known Issues list and patch notes - a lot of areas were indeed addressed beyond the last flight build. But, there are also some areas that the team is continuing to work on. Goal is to get a solid foundational experience but the work doesn't stop once it's "released" (just like there's more work happening on Reach w/ bug fixing and even new features).
