I wait to see if they're on my team...then I back out. I usually play dom so I look at their approximate kill to cap ratio, to see if they even try to play the objective.

Lol, I get called a H4X0R do often because I destroy their KDs apparently, mine is 2.57 and I'm proud of it, but I really don't give a damn about it or yours, your just another player when I play

That's why i loved the combat record in Blops i loved seeing those in the lobby who thought they were good but once the match started they ended up either dashboarding or getting beat

Heck yeah, I love playing against opponents with high K/Ds - my K/D sucks, so maybe I can learn a thing or two by observing them in action.

...Unfortunately, I frequently discover that high K/Ds are not a result of skill. It's often due to other factors, like boosting, dashboarding, and MW3's widespread & well-known lag-related issues.

When many high K/D players find themselves in a lobby where they actually die a couple times, they quickly back-out/dashboard to preserve their stats (thereby nullifying any validity such stats might have).

When I repeatedly hit high K/D players with multiple shots only to instantly die myself, it's clear that the game is just giving them a heavy "lagvantage."

It's just a game (flaws & all), so it's not like my ego suffers if I don't win every match. Others are apparently fragile enough to give stats more weight than they ought to carry.

I'll play against others with high KD's as long as they are not campers.
