Pretty sure it only crashes when I am having an amazing game. That way I lose all of the stuff I gained. Yay.
Oh yes. There must be algorithms that keep track of how good you're doing and then crashes the game when someone does too good. ALL of my crashes have been games where I've racked up a TON of points and was playing really well with lots of kills, resupplies, heals, revives, captures, etc. I get so pissed when those crash and are lost. But the games where I go 10-25 and can't get anything done? Those run smooth as hell and the server is stable for hours!
The crashes really are annoying. It's hasn't been too bad today. My buddies and I played 5-6 hours with only 2-3 crashes, but I'm still kind of paranoid about it. When I play solo I only play domination because those matches are shorter, meaning I won't lose a ton of stuff if the server crashes.
