This just dawned on me, and it's so simple and obvious now that it has that I can't believe I didn't think of this before.
The reason so many of you are seeing your k/ds drop in Black Ops 2 is because of me, and other people like me. People who have always played the objective in CoD titles, going even or negative in many of our matches, but content to be the guys who allow the rest of you to run around collecting dogs and MOABs while we do the dirty work like capping flags and setting bombs. Us folks who got excited whenever we managed to earn an attack helicopter or an EMP. But now, with the new scorestreak system and the much more lethal mid-range streaks, we're actually getting kills, too...and bringing down your k/d in the process.
In BO1 domination, my typical game would start off with capping the home flag, moving towards B, and (if I was lucky) getting a kill in the process of capping the B flag. Then move back into an overwatch position to guard our flags while the "good" players rushed forward to rack up kills & screw up the spawns and the "bad campers" sat in their perch slowly working their way to 10-0. When all was said and done, I usually died right after earning my counter-uav.
But now, with that same start I've earned 450 points towards my first scorestreak. My UAV is already in the air telling you where to slay & earning me 10 more points every time you do, and each guy that I pick off as they try to take away the B flag is netting me 125 more. In more games than not I'm earning my Lightning Strike, often several times, and now that I've gotten pretty good with it it's netting me 4-5 kills every time, which leads to my Sentry Gun. Being objective-based & always thinking about cutting off flankers, I know the best places to put that puppy, too. In an average game I'm netting an extra 6-10 kills from streaks that I never would have earned in the other CoD titles...and those 6-10 kills are coming courtesy of you guys, who are used to earning your high streaks via the gun & riding those to monster scores and k/d ratios.
So yes, the lag is definitely affecting your ratios, too. But me & the other objective players aren't helping, either.
Before I get flamed, I'm not saying that none of you ever played the objective before. I'm only pointing out that more lethal streaks are being called in now, and that's making everyone die a little more often than they're used to. For people who maintained high k/ds in prior games, that's going to lower it this time around. But for people who really struggled with their k/d, it's going to be higher now.
