We want new things.
I have heard so many people say that it is an extension of COD4 or just a Modern Warfare 15 map, map pack. To counter this, change up the perks, the killstreak system, and the game modes.
The perks are a given, just revamp them a little and create a good balance.
The killstreak system should not be just kill based. It should be kill based only in kill based game modes like TDM. In other game types, you need to reward players for actually helping the team by playing the objective.
Game modes are my strongest influence here.
We need new ones. Black Ops had the same playlist as Mw2 with the addition of wager matches, which did not even give you xp towards leveling up. Anybody here remember the game mode 'War' from Cod5? I loved that so much.
You guys should also look at what the hackers have done. Zombieland and Hide and Seek were the freakin shit when I had mods back in the day. You could try to implement those as a mini game or a default private match setup game. DO SOMETHING and create new, completely new, game modes.
Another thing, I think you should create a separate playlist for private matches, where if you want, it can be open for people to join, and you have personalized settings so that you can do your own thing, but with other people who want to do it too. Kind of like how the Cod 3 online was set up if you know what I mean by that. If not, then think of this:
I want to play an hour long game of Team Deathmatch with some friends, but I only have 5 people online. So I start up an Open Private Match Lobby, and I have the settings how I want. I can choose the types of guns to use, the map, and all of the other awesome, in-depth settings that IW has added to the game. When I start the game, I give it a title : Hour long TDM marathon. And the settings will show up in a sidebar in the Open Private Match Lobby playlist. Other people can see this and they decide to join, and soon, I have an hour long 9v9 TDM match going on.
I think that that last section can add so much shelf life to the game. I would love to just play with a bunch of people where it didn't matter what the hell happened, but its still like a regular game if you understand me. Of course, you can't rank up in it. So maybe they should have a whole other section like 3arc did with zombies so people cant glitch it.
Well, thats my thoughts!

Ok heres a list of things i want :
Paint Shop: This is for customizing your guns, so you choose a gun you want to customize.. you get takin into a virtual paint shop/paint garage, you have access to different types of paint ( gloss, matt etc ) LOADS of colours and you can paint your gun with a virtual spray can/and you can use other things aswell.. You could unlock this at a higher prestige maybe?
And a starting prestiges you have the camo`s you unlock by headshots?
2 Heli pilots.. when you get a heli, you can invite 1 team mate to control the heli/man the machine gun
Some1 else posted this: when your heli gets shot down.. you can jump out and activate a parachute
Cycle through your earned killstreaks and choose the one you want to use ( everyone wants this )
Cant think of anymore stuff yet
I love the heli idea, just because teamwork is sexy. Imagine having a duo pair of star players who work together so well and they even share choppers. amazing.
