Griping about Kill Stealing means you should not be playing multiplayer in the first place. combining fire on a single target kills it faster and thus makes it more likely for your team to win
This isn't about concentrating fire, this is about someone who intentionally takes someone elses kill. Working together is essential, yes, but if someone who just walks up and shoots your down after there is no possibility it was an accident, it sucks. There's no reason to, it's common courtesy to let whoever downed the enemy get the kill. It should always work that way.
In other games there usually isn't a Down But Not Out state (or it rewards the downer the kill) so people who didn't play the other Gears might not understand. For the most part in Gears 1 and 2, people didn't take kills (at least in my experience).
So now, when the third is ridiculously popular, all the fools from other 'team based' games come in and constantly steal kills. From what I've seen, it's mostly the 12-19 year-olds who play CoD nearly exclusively. And yes, the kills matter. If it was a competition or league where all that matters is the win, then I'd understand. But this is casual fragging, where whether you win or lose isn't so much an issue as much as having fun. It's not fun, however, when every time you earn a down, the effort gets stolen away by someone too dishonorable to allow you your kill.
