You sir are a complete waste of space and I suggest you read my post again....Take a moment to read the part when I have said "I am not a child and my system is set up correctly for internet gaming".This game is flawed your system does not work.Read the other posts on the forums about the horrendous lag over the last few days(there are lots to choose from) and stop trying to blame other peoples connections.Anybody with the tiniest bit of gaming experience can dish out the so called advice you do.I have seen you give the same advice time and time again.Like I have said this game has problems fix them.......
