Improvements needs on Halo infinite

Hi, I’m a huge halo fan since 2001. I’d like to open a topic to improve the features of this beautiful Halo Infinite beta to try and make it even better. The passes are not audible at all, not even with € 400 headphones. Sometimes I’m behind a wall and I get enemy shots. After winning a match by finishing first of both teams I don’t earn anything in exp. And finally can you put the Battle Royale mode?
Could you please arrange as soon as possible? A thousand thanks! Halo best game in the world!

I’d personally prefer a PvE mode like Firefight than a Battle Royale mode, I’m sure people can make a BR themselves once Forge releases.
