I really can't explain it. In PvE I would of course swear constantly, but it was of a frustrated muttering sort. I would get annoyed but rarely truly angry. Somehow PvP always made me mad. Well, unless I won, then it was nice, but even then I'd find something to swear about.
I can't say it's the PvP aspect, since TF2 doesn't make me swear quite so much. Or when I'd play Mt:G against friends, almost no swearing at all.
I can't blame it on people being stupid either, since a stupid PUG can be just as stupid and probably more of a waste of time; at least when BG dummies zerg the farm-BS bridge I can get honor.
Based on analysis of my profanity, finding patterns in it, I can only conclude that most PvP is, quote, "fucking bullshit I mean what the fuck is this shit?" Let's break that down: I claim that it is fucking bullshit but then I question what the shit is. This leads me to conclude that I actually understand PvP perfectly and have nearly unlimited potential in it, but that some sort of mental barrier is holding me back and I am expressing frustration at this limit.
There are only two possible explanations.
1) The CIA knew that I would be dangerously dominant in PvP and used advanced brainwashing techniques to block my skills, but then to cover it up made me a softy leftist liberal, which also provides a convenient cover for them to kidnap and kill me.
2) I'm actually just really bad at PvP.
Obviously the second one is a useless oversimplification, leading to the only logical explanation: I am a chained PvP god.
P.S. Burn this post after reading it and oh my god they're right behind you.
