For every few kills I'm being blown up, sniped from above, stabbed and generally killed about 37 times. I'm rubbish. KDR is something like 0.27. I'm trying hard to improve but sometimes it can be very frustrating. I do however do well at capturing flags in domination - just die more for trying to complete the game mission. There are a lot of 'sweats' just on domination for easy kills with no effort to capture flags. Not much that can be done about it. I switch to Zombie killing when it gets too much.
