Ohhh I know! Biggest bane ever! You empty a whole frickin' mag into someone, recticle lights up - confirming hits - a split second later you're chewing dust. Or the number times I've watched the killcam and seen myself shooting over this guys shoulder, even though the hits were connecting right in the centre of their chest. It's probably the one major thing I hate about this game, asside from certain player habits.
BUT saying that World at War was just as bad, but it didn't find a new host if the host left. Can you imagine the frustration if the game ended prematurely EVERYTIME the host left? Yeah, I know we get it now and then, still, but could be worse?
Bring on Black Ops.
