I know there is a hundred different topics on this situation, but this tackles some of them head on, and even things I didn’t see.

LAN Profiles Don’t Have Everything Unlocked
-This is key for events and competitions. Without the ability to create custom classes using all of the game elements, events are forced to use predetermined loadouts or force players to bring their own profiles.
Lack of Precision Forge Controls
-Reach’s 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.
Grifball “Ball Arm Time” Is Bugged
-Setting the Arm Time to any other setting than Instant does not actually change the Arm Time.
Cannot Move While Having The Scoreboard Up
-Another feature that has been removed without explanation. Players in past Halo games could bring up the scoreboard and still move their player around. In Halo 4, pulling up the scoreboard negates any ability to move your character.
There is a post about this: https://forums.halowaypoint.com/yaf_postst195722_In-game-scoreboard-needs-update-in-TU.aspx that addresses this issue in full detail.
Setting Ammo Count for Battery-Based Weapons in Forge Does Nothing
-Changing Ammo Count for batter-based weapons hasn’t 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 Or When Dropped After Death
-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.
Tactical and Support Packages Earned Through Specializations Are Not Options In Custom Games
-It seems very unnecessary for these to not be included as options in custom games. Things like Rogue, Stealth, etc. are very desirable for Custom Games.
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.
Forge Pieces With Invisible Barriers, and Other Various Piece Glitches
-Some pieces, like the Tower, 3 Story and some of the Rock pieces have invisible barriers that block shots coming in and out. When walking on a Wall, Coliseum (especially on Erosion) players appear to be in a floating state where their legs are raise as if they are jumping, and glide across the floor.
Setting Respawn Time in Slayer, Infinity Slayer, KotH and Oddball Gametypes Does Not Negate Instant Respawn
-Instant Respawn is always an option to players during a game no matter what the Respawn Duration setting is set to.
Inability To Set Ammo Amount on Initial or Random Ordnance
-In Halo 3 and Halo: Reach, you were always allowed to set the amount of ammo weapons would spawn with. When spawning weapons through Ordnance, you do not have this option any more. This is especially an issue with Initial Ordnance.
General
-option to disable Sprint
-restriction lists (ability to dictate which Primaries, Secondaries, AAs, Support and Tactical Packages can’t be used)
-option that is Bottomless Clip that doesn’t also give you infinite ammo
-ability to dictate Traits for each loadout
-Race. Pretty please?
CTF
-option to turn off auto-pickup
-option for flag-juggling
-1 Flag, 3 Flag, and Neutral Flag support
-Stockpile support/sub-gametype
Oddball
-Ball Throwing toggle
Flood
-Allow alternate weapons for the Flood
-Ability to change loadouts
-Safe Haven support
Regicide
-Juggernaut support/sub-gametype
Loadouts
-Ability to diable “starter loadouts.” These are the two extra loadouts that appear at the beginning of a game, and just modifying these make it very restricted what you can/can’t do.
Ending Score isn’t team themed
-You know when the game ends and the scores sweep from the right? The color is always blue. It should be themed with your team, so if I was red team, it would be red, or yellow, or green, or pink.
