It only matters in Instant Action and Team Instant Action! Fine...keep stats for K/D for those gametypes...for the others, they should keep them separate. Play those games if that's all you're worried about. Unfortunately it's way too easy to get your ratio up on the other gametypes when you play for yourself, and don't help your team. I have gotten on many peoples cases in the lobbies for saying "hey man I got so many kills...look at my K/D!", and the game we just played was Capture the Relay...c'mon man, you did absolutely nothing to help your team win! Many times I have been the only one on my team who has actually gotten relays and our team gets killed...but guess what...everybody else has a positive K/D ratio. Get over it. Seriously people...who the heck cares?
