This is gonna happen to everyone with good k/d well..i mean if there aren't any noobs to pwn then you wouldn't have a good k/d and these "noobs" will consist of teammates and enemies lol.
Besides its fun to "control" the game whoever is on my team wins and whoever isn't loses
If you don't want to "control" the game then run around with a sniper and let someone else do the controlling
I also agree about the having at least 3 good players on your team=win
I mean just 3 people with above 2 k/d will give 100% victory in tdm
