First of all, your list of issues don't even come close to the full list of every persisting issue in Halo 4. It's a teeny tiny list compared to the full one.
Now, to respond to all of them...
-Maybe. Never liked it.
-You just complained about armor unlocks not being here, now you get annoyed that guns can be unlocked? Not like it takes a long time to unlock them. Plus, Loadouts don't affect gameplay if people doesn't want it to.
-This IS Halo. Halo 1 never had duel wielding; people complained. Halo 2 never had equipment; people complained. Halo 3 never had bloom or AA. People complained. I really don't find it surprising people complain about Ordinance. My main issue about it is how 343 doesn't offer a competitive playlist that completely negates the randomness of Ordinance.
-Not really. I just feel like Blue and Red has too much white mixed in.
-The Plasma Rifle is no longer in this game. Deal with the fact that the Storm Rifle is better.
-Forge World? What a joke. I'll always miss Halo: Reach's forge world. With all the customs I played on it, its almost a second home. Ravine barely compares; the lack of Forerunner pallets make me go ???. It's tiny. We used to be able to Forge on Alaska, Montana, the Canyon, cave, the sea, the island, the grifball cave, the flat plain above it, the air, many places. In Halo 4 each locale is severely limited.
-Can't argue with you there, precision editing + zoom easily made Forge 2.0.....well, the best Forge to work with. Ignoring the limited custom game options.
-BR sounds like an actual gun. An M16 and SCAR firing a 3 round burst sounds bad? Ooo-oo.
-Lets just say, Forge in Halo 4 compared to Forge in Halo Reach is a downgrade. Magnets don't work properly. If implementing an idea, 343, don't break it.
-Personally, I played campaign for campaign and not points, but thats just me.
-This doesn't matter to me. Although the shapes may be changed, it doesn't stop people from forging good maps.
To add? Errr....
-Lack of actual competitive playlist
-Overpowered pocket shotgun available at spawn that can easily trump Shotguns.
-Camo campers not being punished.
-Randomness.
-DMR makes all other Primary precision weapons obsolete except maybe the Light Rifle.
-Theater availability is terrible with the lack of Spartan Ops and Campaign filming.
-Forge Glitches from Halo 3/Reach are STILL not fixed. 3 years spent on what,343?
-Campaign Glitches. Even my 5 year old cousin is clever enough to make sure, if designing a Forge map, to have no places where people can sneak out. 343? 'Lets have an entire level where you can skip to the final part of just by jumping through a hole!' 'Lets create levels whose every fight you can skip using glitches!'
-No Elites for 'canon', adds in Flood as a replacement which canonically is stupid, and gameplay wise is worse than Infection and Theater wise useless
-Lack of Invasion
-Spartan Ops doesn't actually advance story each time you play it, and features repetitive levels where all you do is kill enemies and click buttons while lagging like insanity.
-Fileshare unavailable for 3 months after release.
-No skill ranking except for CSR, released 6 months after game release.
-CSR not visible unless you have a laptop/tablet/android/iphone beside you.
-No competitive playlist till tomorrow
-Spartan Rank 130 can be reached easily.
-Bad voting system
-UI is a HD degrade from previous games
Obviously tons more.
