Yes, and that is reflected by your contribution value in those games.
Going 10-1 is better than going 30-22 and 20-12 -- but not better than going 30-20.
Contribution average is a simple formula:
Kills - deaths / games played.
However, camping is frowned upon for good reason, even though it definitely is the most effective strategy -- unless the other team also uses it. Which is the problem, as discussed in the other threads:
It's a prisoner's dilemma.
But I can go 30+ and >5. That's +25 vs. +10. And the funny thing is, I have done that and told the opposing team in advance where I would be and what I would be doing, my entire loadout, and where I would plant claymores/IEDs.
You're too focused on both teams using the strategy when, in fact, that simply does not happen in multi-player. But I'll address that in the other thread. Let's stay in one thread. Camping threads is not frowned upon.
