This is a copy/paste from The Halo Council which has several issues that need to be fixed right away. OP, I think you should put āOfficial Issuesā in your title so maybe it will get more views.

Game Announcements (Multikills, Sprees, etc.) Are Not Made In Theatre Clips
-When you create a clip from a full film, the announcer no longer is audible.
Lack of Precision Forge Controls
-Reachās Forge controls allowed players to move objects slower and more precisely when holding in the Left Analog Stick. Additionally, players were able to zoom in on objects with the Right Stick to get a better handling of their precision movements. These controls have been removed without explanation.
"X" Waypoint for Dead Teammates No Longer Exists
-Another feature that has been removed without explanation.
Grifball āBall Arm Timeā Is Bugged
-Setting the Arm Time to any other setting than Instant does not actually change the Arm Time.
Geometry Holes on Ragnarok
-Holes have been found in the geometry of Ragnarok, most notably in the rock slabs to the left of the ābeachsideā base and on top of the bases.
Lack of Party Indicators In Matchmaking
-Another feature that has been removed without explanation.
Party Details Tell Significantly Less Details in Halo 4
-Another feature that has been removed without explanation.
Setting Ammo Count for Battery-Based Weapons Does Nothing
-Changing Ammo Count for batter-based weapons hasnāt had an effect every since Forge was introduced in Halo 3. Surprising to see this bug make its way into another game.
Weapons De-spawning Too Quickly If Not An Ordnance Weapon
-Players have noticed that weapons are despawning at a ridiculously quick rate after they have been dropped in comparison to past Halo games. This makes drop-spawning weapons (which creates static weapon spawns) a very inefficient method to spawning weapons.
Games Beginning With No Players On Opposing Team
-Games will somtimes begin with no players on one of the teams. This usually occurs when an entire team backs out after a game or the game after a game has ended because the entire team quit out. This bug is costing players Double XP games.
Alphabetical Order For Active Rosters
-Really confusing when you try to look for specific players through your Active Roster. Essentially forces you to just scroll through the entire Active Roster to find players.
Tactical and Support Packages Earned Through Specializations Are Not Options In Custom Games
-It seems very unneccesarry for these to not be included as options in custom games. It almost seems as if this was an oversight.
Cannot Change Max Player Count of Lobby Once a Player Joins
-Very annoying bug. Requires the leader to leave the party and make a new one to set a new Max Player Count.
