I've never come across a game that does this o_o

Edit: Shooter that is.

I'm not really fussed with it. I was annoyed at first because it started happening after the first cod4 update, but I realise now it's a blessing.

Why? Well it ensures that the teams get mixed up after each round. When you come from a relatively small country like Australia, you tend to run into the same 50 people online most nights. It's always nice to know that even if you're getting your ass handed to you this round, chances are it'll disconnect at matches end and you'll connect to a new lobby with the exact same players, and the teams will be randomised again.

EDIT: Should be noted that this is on the PS3. and I was exaggerating about the 50 people, it's more like there's 50 I always run into mixed in with people i've never played against before. Still, it's more balanced out.
