Really not fair to the other team if you leave and not giving them the victory. If you leave you forfeit and lose..though hats how it should be. I agree it's stupid that you can't back out if you want to ,though. It isn't breaking the game in any way. Why Bungie did this is beyond me. Who cares? If you feel like you're going to get your ass kicked...Why should you be forced to stay. I've never left a match...never will...but this was completely unnecessary imo.
