i think it be really awesome if the matches were saved and recorded, and we could rewatch like we can in Halo 3.
be able to watch it from POV or free fly watching the match from any angle
it be great to rewatch awesome moments in matches we did and share on youtube for our friends to watch.
and speaking of youtube, that be great since it help get people watch these cool highlights and bring in more people to the game 
In the meantime, if you have Twitch, you could always stream; you can save and share your videos and create clips pretty easily that way. It’d work until that’s implemented in-game.
