I get more angry than I should at a game but if I have more than two bars and i'm not doing well, I have to remind myself that I have nobody to blame but myself.
If your playing on two bars and the game is very laggy, my suggestion is to stop playing all together. Theres nothing worse than losing because latency from your service provider is bogged down.
Exactly, I think mine ties though into the rage quitter post because I usually find people with high K/D tend to rage quit a lot more (again, I could be just generalizing here but it is what I have encountered). You are not your 5.75 K/D.
Also, this game is not for you if your doctor says you already have high blood pressure
