If all you do is sit in the corner and "strategically" camp, that isn't a singles hitter, it's a guy who hangs his elbow over the plate.
When I first started the Call of Duty series and began to play online, my download speed was at 3, and I rarely saw three bars. I had no incentive to check my connection against everyone else, so I resorted to playing strategically.
I developed better skills now that my download speed is 10, but I play much more effectively without running around. The random teams I play with usually consist of runners, and I try to hold spawn. I have something your average player doesn't, and that's patience.
I don't play the game like a race to 75, but if 6 players had my numbers, we would win every match 75-39. The best matches I've been involved in were much lower scoring than that.
Listening to the same leading scorer on the other team bitch about my camping, as he comes back to find me in a different spot, is truly the most satisfying part of playing the game.
