Depends on how good my team is and I bet the same goes for the people who speak here as well.
It pisses me of when someone tries to claim they single handedly 'dominated' the enemy, when it is team based play, because they never seem to grasp the fact their team mates did a lot of the work. They ignore the fact their team mates could of wounded the guy down to single digits before you got the point for killing them. These people feel so smug when they pick of a sniper that killed a team mate just blindly charging over open ground, ignoring the fact they never knew the sniper was there till he took that shot. Never will you see them giving thanks to someone who covers their back, ensuring they don't have 'down time' waiting to respawn.
Every time I have done well is because the rest of the team where there to ensure I was not overwhelmed. Think you could remain dominating if you were the only person playing against their whole team... or would you wage quit because it will be such a one sided match where you get your arse handed to you?
So when you find yourself seeming to dominate the enemy, thank your team mates for making it possible. Without them, you are NOTHING!
