I think Destiny made some odd choices with their voice acting picks, and from what I've read on here and /r/destinythegame there may have been a lot more V.O. work done that was cut later in the game's development life, but I'd love to see Crucible incorporate each of the Vanguards voices and maybe the Faction leaders, much like we hear them when doing Patrol Missions, as Crucible announcers. It's a small voice over job and it could be a cool little DLC free or paid and I think having the option would be something cool that I've never really seen in an FPS....Or have a contest with fan submitted announcer voices and add that winner into the pack too (since it's such a community driven game and all).
