Just checked out the most recent bulletin on Waypoint and found a little information on the upcoming TU for Halo 4:
• Reduced the range of the Boltshot’s damage scaling over distance. The previous effective range for 1-hit kills was 20'-25'. The range has been reduced to 15'.
• Fixed an issue that did not allow players to create respawn timers or disable instant respawn in custom games.
• Fixed issues with friendly fire against vehicles. If FF is disabled, damage / EMPs from friendly sources will no longer damage vehicles that are fully controlled by your team.
The last point I thought was very interesting. No more FF for vehicles in BTS. That should end a lot of rage for you guys.
