why would i work as a team when i can get mad killz and improve my k/d

Couldn't agree more-however you have to take into account that a large amount of those people have been playing FPS games that don't require teamwork and therefore they are accustomed to running around like headless chickens.

Get the fucking objectives, propaganda mode and no ones protecting the dude with it, assassination and no ones protecting the target, S&D and I'm literally the only trying to plant the fuses. Everyone else is just sitting in the opposite corner of the map, and then at the end I get asked how I came second when I only had 18 kills. BECAUSE ITS NOT TDM, GET THE OBJECTIVES!!!!!!!!

I had the exact same complaints with the Killzone 2 multiplayer. Now, I'm not amazingly skilled, but the multiplayer goals were always clear to me. Regarding specific objectives, it often seemed that others were clueless, or otherwise assumed that someone else would take care of things. That rarely worked out in my favor, and after a few hours, I had to walk away, never to return.

@Pessh: The last sentence of your post compliments your avatar quite nicely; I enjoy that. But seriously, I agree with you.

Its so disheartening when you die, look round for a medic and realise you're on a team of snipers. I've been trying to play as a medic, but you have to be quick because people are just hammering the respawn button so they can charge into enemy territory, throw some grenades, and die again. It seems a brilliant game when it all comes together and you're on a decent team, but if not its just frustrating as hell.
  
@Pessh:  
Sorry about that. But I didn't mention kills, just wondered what you'd done. A COD style "so and so" defused the bomb etc notification would be a good idea.

That's why I like playing the objective based stuff in COD. Everyone else is just running around shooting eachother, so I just go all ninja with my tactical spawn and capture everything. Usually there's just one dude to deal with hanging out by the objective. You know the other guy that knows where the real points are at.

The ones who control the spawn points control the game.

There are really different games when I have played it. Sometimes everyone just runs around and doing nothing, but sometimes everyone is on the ball. Assassination target goes to easily defendable position, everyone puts mines on the doorways and medics revive the fallen... It's a beautiful thing.  
 
I have played a lot of MAG and sometimes it's awesome and sometimes it's frustrating. The best thing to do is to join a active team of players. KZ3 is better than MAG in that you only need a few co-operating player to dominate. In MAG you need a lot of people (my clan has sometimes 60 players playing at the same time). Also when time goes by the quality of the players go up a lot. I don't know what you expect for a open beta. There is a lot of people just checking it out because it's free.

It's all relative. If everyone else is just killing each other it's easier for me to get shit done.

Tons of gamers play all shooters like CoD. They spawn, run around looking for kills, die, rinse and repeat. I see this in Killzone 2, Killzone 3 and Battlefield Bad Company 2. I always try to play as a member of a team and get the objectives, but find it uber frustrating when I'm running around trying to revive people, yet my whole team is full of infiltrators and snipers without a medic in sight. In KZ2 I got revived all the time, I hope this is just due to the beta being so fresh, and hopefully people being pulled in that have never played Killzone before and don't know what to do. 
 
I prefer objective based game modes because it adds another dimension to just running around and killing dudes, but the majority of my friends always prefer to play Deathmatch game modes only and hate doing objectives because of the objectives being camped and us running into a cheese grater. lol

What does that have anything to do with it? "

Snipers are the worst. On average.

More medics would definitely be good.  I usually end up as the only one on my team.  I always end up in a situation with two or more teammates down waiting to be revived.  Given that you have to wait for revive to recharge after using it, I lose a guy because they get impatient and respawn or I get shot while I'm waiting.

So many Snipers...

Pro Tip: Unlock Marksman cloak +, scrambler + and the Helghast Assault Rifle. Activate cloak. Complete every objective yourself.
 
Alternately, try out the tactician. Dude, you can capture spawnpoints, call in drones and see everyone everywhere. Run into a building, hit radar and murderfy thems asses.

Welcome to the world of online FPS! At least if you go with randoms. (Which I also do almost exclusively.) 
 
I think they made some interesting choices here. The took away the assault class, and made the standard "assault rifle guy" the tactican, which is the class to battle over map control.

quality team mates are super tough to find.  especially when there is k/d tracking.

The best team I've seen so far had tons of medics and constantly rezzed each other.  Also having the medic unlock that allows you to rez yourself seemed to be in practice as well.  Seems like a similar trend from Bad Company 2.

I was really pleased to see that during the last few days of the beta people seemed to "get it" much more. The quality of players seemed to go up (or I had a lot of luck) and I had some really tense 3-4 games.
