Yeah, I'm not on PC often, yet. Not a good enough rig, but on PS3 I experienced similar situations. So I've adopted the phrase "I can do bad ALL By MySelf!!" for when things are just too dumb and not enough teamwork is happening and the internet is not working so well or whatever is happening and I'm getting too pumped and angry; so I switch off to a older, Better game. Usually Virtual-On: Oratorio Tangram or Something where you Can't die instantly, unless it's a platformer with death-pits or something.
