To start off I love all the halos. I just like Reach the least because of it’s multi-player. I think Bungie did a good job but it is completely different than any other halo.
This is for Halo 4 and on…
Bloom is a problem to me because it is just frustrating when your reticule is in the perfect spot for a head shot but the bullet goes to a different area in the bloom. I’m just saying bloom wasn’t in the other Halos, why fix what isn’t broken???
I think the animations are cool when you assassinate but i don’t like the feeling of not being able to do anything. It needs to be speeded up and not be so sensitive when you just want to back smack.
Hit Scan is good keep it in!
Jump Height needs to be higher like it used too.
I love how now when you snipe through the body and out of the head it counts as a head shot! Love that!
I don’t really like when you are getting shot how it it moves or pushes you. (I’ve been sniped in the body and it push me off the map several times, dmr too)
Maybe a broader range of weapons? I can tell from the halo 4 trailer that weapons will most likely be customizable. (Pistol in the video)
I know this has been in all the halos pretty much but I think the beat down lunge should be dumbed down a lot! I shouldn’t be able to be a foot away from you and still be able to hit you. I’m guessing that has to auto aim? lol it’s like a super power or something.
Very important is how the frag grenades react to the enviornment, I hate it when i try to bounce a nade and it just stops and gets stuck. They should at least roll as much as the -Yoink!- oddbal! lol have you ever dropped it on a slope? You will spend some time chasing it. -_- Also it seems like they do a lot of damage even if you are barely in its blast radius, it be great if it didn’t do as much damage around the outer most radius of the frag grenade explosion.
Oh and if your going to keep armor abilities…
Then sprint should be fixed to where when you jump off of something and land on the ground and hit the sprint button you don’t start running like a cartoon character where you stay in one spot while running. Same thing with evade, I don’t like rolling in one spot with out any movement. Camo should not fade when you move, it’s only worth getting if your going to be standing still or moving slow.
Personal Preference: I don’t like the other armor abilites. Jet Pack ads a dimension to maps and ruins a lot of them for reasons of how much easier it is to get to certain areas.
The sniper in Reach is too easy to use. Make it like it was in halo 2/3. I’m too damn good with it in Reach lol
I do like health in halo, just the melee is too crappy, I believe it should go threw the shield and to the health if they have previous damage to there shield. That is much more fair than a guy full shield a guy about to be one shot ending up even from trading melees.
The DMR and Pistol just seem like they should have a bigger clip, just a little bit. But that’s only if your keeping in bloom of course.
Oh and I know this next one is a long shot but dedicated servers for Halo would be awesome instead of selecting host. Equal playing field for everyone! 
The armor in Reach is too bulky, everything sticks out too far from the body.
Forge is great, just too much grey, makes it hard to remember the maps that people make, Maybe make it to where you can completely change the color of the object or have an actual picture of the map when in the MM lobby, instead of every custom map having the same picture of Forgeworld.
Firefight voices should be able to be used in MM! It would be hilarious for your spartan to make fun of people for you!
Snipes somebody in the face Buck says,“How did that bullet taste?”
Sorry this is long but I really love the Halo universe and care deeply for it’s future gameplay in MM. Thank you 343 for taking care of Bungie’s baby, I have faith in you!
