I figured I'd post this here too:
So I've made a list of my ideal gameplay balance changes. It's not that I won't love the game unless they do these, this is just how I personally think the game could be greatly improved. Sorry, this wasn't written in a very flavorful manner.
Weapon balance:
-DMR can stay the same; it's the other primary weapons that need a little something extra injected into them.
-BR should either slightly increase fire rate or decrease it and make it a 4 shot kill. I say increase it a little because LR is 4 shot already, plus a closer range 4 shot primary may be a little unfair because it would be easy to land all 4 shots in closer quarter combat.
-LR is nearly perfect, but I say up the fire rate a hair to make it on par with the DMR.
-Carbine is better than 3's carbine, but I still think it should take one less shot. Because it takes more shots than the other longer range primaries, that means it requires more precision. As it is right now, I would functionally choose BR over carbine everytime.
-Assault rifle is powerful, but I think it's fine. 50 feet or more and the longer range weapons win everytime.
I haven't really used any other primaries very much so I can't say anything.
-Magnum should be 5sk.
-boltshot is perfect.
-plasma pistol is fine.
Power weapons:
-SAW is really fun but definitely decrease the amount of ammo you get, and possibly the magazine size.
-Needler is also fun, but a little too powerful. Make it slightly less magnetic. In previous Halos if an opponent was strafing correctly away they could avoid the needles, now it doesn't matter at all, its point till red, then kill (very quick kill too). You should have to juke your way to a kill like in previous iterations, thats what made it require some skill.
-Incineration cannon and rocket launcher are too strong. The stuff that bounces after the initial explosion shouldn't do so much damage. I haven't missed with either of these weapons yet. They can be powerful, but the radius and therefore lack of required accuracy is silly. Go back to the power of the Halo 3 launcher (and possibly keep the increased velocity to account for sprint).
-Shotgun is near perfect.
-Scattershot is possibly slightly overpowered but I really like it the way it is.
-Sniper is good
-Beam is too good, but I can deal with it.
-I actually like the Binary rifle, it's too powerful but the magazine size and the rarity factor make it okay to me.
-The Hammer is okay, but what happened to the opponent's body flying 100 feet every time? Most the time they just smack into the ground now, no fun!
-Concussion rifle is okay but was somehow cooler in Reach.
-The sword is pretty much right on.
-Sticky detonator is pretty good...make the range with grenades similar!
-Railgun is awesome the way it is.
-Laser is not too much of a problem.
-I think all grenade types need increased damage radius. It's crazy how you can get 3 shots on a guy, throw a grenade 5 feet away from him and have him survive. Promethian grenades would benefit from a bigger radius because they would then be able to actually block hallways/paths.
AA balance:
-Jetpack isn't actually that bad. It still ignores the map flow, but it also makes the player more vulnerable. I still think its kinda silly, but I can deal with it unlike in Reach.
-Hardlight shield is fine.
-Thruster is fine, even though other people seem to think it's weak. It's my go to AA and I'm constantly evading danger. Only thing I wish was that it was in first person.
-Hologram is nice.
-Regen is nice, not overpowered, not underpowered; just enough to get your shield back without being invincible.
-Active camo is another one I think is pointless, I see kill cams of people who use it and they're just standing there, waiting. It won't get you that many kills.
-Auto Sentry seems fine.
-PV is cheap, but close watch of the radar keeps it in check (in infinity at least).
I don't have many complaints about tactical packages. I would always either use mobility, shielding or grenadier, but I think they all have their place.
Same thing with support upgrades pretty much; I only use dexterity and have little reason to use anything else. However, I say get rid of the explosives one though, because grenades should be more useful for everyone. Something normally so paramount to gameplay in previous Halos should not feel like its nerfed for everyone except for the person that chooses it as an upgrade.
The vehicles are okay, but I think they are too prominent right now. Make them all more vulnerable to non-power weapons. Oh, but get rid of the scorpion, it's just stupid and takes up room. I also hope maps like exile and ragnorok will be in regular infinity playlists without so many damn vehicles.
Sorry if that was a boring read, I was just listing what came to mind. Let me know what you think.
edit: I don't like the changes to the radar. It looks like the range has been increased, and I don't care for the red arrows pointing where someone is outside of the radar.
