Its sad what its turned into. That is pretty much why I stick to TDM, the objective modes are unplayable. Have you tried HC modes? It seems that I get a little less of this nonsense when I have played HC objective games.
Hoping that Black Ops II makes some serious changes in the Objective modes. Take K/D out of the picture and make the objective the focus. If they bring back KC, make it so you don't get the kill if the tag isn't collected.
The YouTube generation is killing CoD in some ways, taking the focus from Team Play to selfishness.
This is why Stats don't matter, they can be manipulated in the ways you are describing.
People rage at the game, they should be raging at the community as well for this kind of behavior. But as far as the developers, they should have learned by now that if you give this community an inch, they will take a mile. I made a thread in the BlOps II forum stating that I think the Devs should have a group of Ten Year Olds come in and play the game for a week solid. Then, observe all the little exploits they find, and take anything they like out of the game. The community needs to start to man up, and the Devs need to put more thought into their final product to keep these exploits from ruining the game.
HC objectives are nothing but tubers anymore. Since they aren't very effective in core, most of them came over to HC:Dom & HC:CTF to get their fix. Blast Shield doesn't do anything to counter it, either. Prepare to rage just as much.
The OP's best bet would be HC:S&D, if they aren't upset by the fact everyone runs vests.
Don't think that would be effective.
The only fix is to make K/D irrelevant in objective modes. Make the XP gain for objective play significantly higher. Make it so that your K/D doesn't count towards your stats in objective matches, but triple the XP for defensive kills or for taking out a bomb carrier or defending a position, and allow those kills to count towards your overall stats. Caps, returns, plants, defuses... those should be the big focus.
In KC, kills should not be counted unless the enemy tags are collected. As it stands, people just sit back and count up their kill count while ignoring the tags, basically legal boosting.
You can't punish non-objective players, but you may lessen their impact by taking away the reasons they do what they do. Players use the objective modes to pad their stats, ruining the game for those who play the objective matches as they are intended.
You forgot about these modes:
Capture the Flag: people camp their flag which is understandable but spawn trapping goes on basically rendering the mode unplayable.
Sabatoge: People don't plant the bomb and instead camp the enemy spawn points for a MOAB.
Team Defender: a cluster fest around a flag that someone camps in a corner babysitting it.
Capture the Flag: same as MW3
Sabatoge: Same as MW3 except for racking up kills.
Capture the Flag: cap one flag and babysit the flag for the remander of the match, possible spawn trapping for nukes
Sabatoge: Same as MW3 except for nukes
Capture the flag: hackers
Sabatoge: more hackers
Basically, every objective mode in COD is ruined by people being greedy over kills.
I feel your pain, nicedrewish ... but they aren't going to take kd out of any part of the game. That's part of what makes COD COD.
What if they had a game mode where you had to enter a code to enter the mode? Then it would be easier to report children being in an adult lobby. The mode could also have more strict rules regarding good sportsmanship.
