Proximity Chat

[imahunting13]

I was just wondering if anybody knew of any information about why proximity chat was removed and if it may be introduced in an update, because some friends of mine and I played custom games together, and the custom games we played sometimes implemented the use of proximity chat so those games do not work anymore. Please let me know if anybody knows anything. I would appreciate any information and if any of the creators see this I would greatly appreciate proximity chat being introduced into Halo 4 in a future update. Thank you.
