Obviously before voting please see my vision of how Halo 4 can be near-perfect. I’m not saying this as some professional in the world of gaming, only as a dedicated fan since the days multi-player clan matches in Halo 2. I also think Halo 4 is a good game, but only marginally better than Reach and not as good as Halo 3. I’m also still playing it at level 69 which is a good sign.
Also please keep in mind this vision will still be massively different from any other Halo and I hope in your mind an improvement 
This is partially to prove my point and also a bit of wish fulfilment. Imagine for a second in a 343 Weekly bulletin in the future they release a massive (realistic) patch that completely redesigns the game, here it is:
-The ranking system is to be returned to Halo 3s with some minor changes. Now, you need to be genuinely skilled to reach a high rank as well as play social games. It will also mean the team works together for the win because that’s the only way of getting XP. The only change is the level “lock” you experienced in Halo 3 won’t be as severe.
-Because we know how much you love Halo, there will be some classic Halo maps to be added to Halo 4 with slight changes. We still want to do our own thing but we will be releasing every Halo multi-player map ever released to be available for the community to vote on. Every two months we will pick the top community-picked map and implement it into Matchmaking.
-We’re also bringing back Foundry and Forgeworld for the Forgers out there!
-Current in-game abilities such as “Ammo” and “Explosives” are to be removed immediately. We recognise they only create problems, because to implement them we had to limit ammo and decrease grenade damage so the perks weren’t overpowered.
-Only some abilities will remain like Jetpack, Invisibility and Regeneration as they still add more variety without going overboard.
-Grenade damage and ammo will be returned to as it it should be.
-The Boltshot will be a Primary weapon now, as we realise it’s overpowered for a secondary. It will have considerably more ammo.
-Scoping while being shot will now be impossible to maintain. It promotes more skill.
-Weapon drops will now return to how they were in previous Halos. It was much better. Ordinance drops will stay though to encourage killing spree’s etc.
-DMR will be balanced while still having advantages/disadvantages over the BR.
-Playlists like Team Snipers, Swat, Big Team Objective, Multi-team and Team Doubles will be permanent and we will throw Regicide in a volcano, never to be retrieved again. Not even by Terminator.
-And finally we will actually listen to the community, because you play the game every day and although your decisions individually aren’t always amazing, as a community and a majority you are the ones who know best. Also when Microsoft say we should make the game more like COD, or “other FPS shooters” we will say “no!!” because this is Halo… and Halo doesn’t need all that ****.
